1 Peter 2:22 Gill

Who did no sin,.... He was in the likeness of sinful flesh; he looked like a sinful man, being born of a sinful woman, and keeping company with sinful men, being himself a man of sorrows, greatly afflicted, and at last put to death. He was traduced as a sinner by his enemies, and had all the sins of his people on him, which he bore, and made satisfaction for, and were the reason of his sufferings; but he had no sin in his nature, nor did he commit any in his life:

neither was guile found in his mouth; though it was diligently sought for, by the Scribes and Pharisees; there was no deceit in his lips, no falsehood in his doctrine, any more than there was immorality in his conversation; he was an Israelite indeed on all accounts, and in the fullest sense of that phrase; reference is had to Isa 53:9 and this is observed, partly to show that Christ suffered not for himself, or for any sins of his own, but for the sins of others, for which he was very fit, since he had none of his own; and partly as an argument for patience in suffering; for since Christ suffered, who had no sin, nor did any, nor could any be found in him, charged upo him, and proved against him; and which sufferings of his he bore with patience; then how much must it become sinful men to bear their sufferings patiently, though they may not be criminal with respect to the things for which they suffer, but yet are so in other things, whereas Christ was not criminal, nor blameworthy in anything?

Isaiah 53:9 (KJV)

9 And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.

neither was any deceit in his mouth: no false doctrine was delivered by him; he was no deceiver of the people, as he was charged; he did not attempt to seduce them from the true worship of God, or persuade them to believe anything contrary to the law of Moses, and the prophets; he was no enemy to church or state, nor indeed guilty of any manner of sin, nor given to any arts of trick and dissimulation; see 1Pe 2:22. Some render the words, "though" (y) "he had done no violence", &c. and connect them with the following. Gill

I've often wondered if Nathanael was reading this passage?

Joh 1:45 Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph.

Read all if 53..... It is just that about Jesus.

Isa 53:1 Who hath believed our report? and to whom is the arm of the LORD revealed?

Isa 53:2 For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him.

Isa 53:3 He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not.

Isa 53:4 Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.

Isa 53:5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.

Isa 53:6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.

Isa 53:7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.

Isa 53:8 He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.

Isa 53:9 And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.

Isa 53:10 Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.

Isa 53:11 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.

Isa 53:12 Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.

Jesus later clearly taught from the scriptures about himself.

Jesus in the Old Testament

Joh 1:46 And Nathanael said unto him, Can there any good thing come out of Nazareth? Philip saith unto him, Come and see.

Joh 1:47 Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!

in whom there is no guile; not that he was without sin; nor is this said of him; nor was he in such sense without guile, as Christ himself was; but guile was not a governing sin in him: the course of his life, and conversation, was with great integrity, and uprightness, and without any prevailing hypocrisy and deceit, either to God, or men. This Christ said to show how much such a character is approved by him; and that he knew the secrets of men's hearts, and the inward frames of their minds, Gill

Joh 1:48 Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee.

Jesus answered and said unto him; in order to satisfy him, how he could know this inward temper of his mind, and to give him some undeniable proofs of his omniscience, which he himself must acknowledge, being such as none but an all seeing eye could discover:

before that Philip called thee, when thou wast under the fig tree, I saw thee; in which words Christ gives two instances of his omniscience; the one is, that he knew Philip had called him; he was privy to all that passed between them, though they were alone, and the conversation was had in the most private manner. Christ knew what an account Philip had given of him, and what objection Nathanael had made; and what an invitation Philip had given him to go along with him to Christ, and judge for himself; which is here meant by calling him, and with which he complied: and the other is, that he saw him under the fig tree before that: he was sitting under it, as men in those countries used to do; see Mic 4:4, where he might be reading the Scriptures, and meditating upon them; and if, as some observe, he was reading, and thinking upon Jacob's dream, concerning the ladder which reached from earth to heaven, and on which he saw the angels of God ascending and descending, the words of Christ in Joh 1:51 must strike him with fresh surprise, and give him another convincing proof of his omniscience: or he might be praying here in secret, and so acted a different part from the generality, of religious men of that nation, who chose to pray in synagogues, and corners of the streets, that they might be seen; and likewise proved him to be what Christ had said of him, a true and rare Israelite, without guile and hypocrisy, which were so visible and prevailing among others. It was usual with the doctors to read, and study in the law, under fig trees, and sometimes, though rarely, to pray there. It is said (t),

"R. Jacob, and his companions, were "sitting", studying in the law, תחות חדא תאינה, "under a certain fig tree".

And the rule they give about praying, on, or under one, is thus (u):

"he that prays on the top of an olive tree, or on the top of a "fig tree", or on any other trees, must come down, and "pray below".

It is said of Nathanael, in the Syriac dictionary (x); that his mother laid him under a fig tree, when the infants were slain, i.e. at Bethlehem; which, if it could be depended upon, must be to Nathanael a surprising and undeniable proof of the deity of Christ, and of his being the true Messiah; since, at that time, he was an infant of days himself, and was the person Herod was seeking to destroy, as the Messiah, and king of the Jews,

Joh 1:49 Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel.

Joh 1:50 Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these.

Joh 1:51 And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man.

Barnes adds...

Before that Philip called thee - See Joh 1:45.

When thou wast under the fig-tree - It is evident that it was from something that had occurred under the fig-tree that Jesus judged of his character. What that was is not recorded. It is not improbable that Nathanael was accustomed to retire to the shade of a certain tree, perhaps in his garden or in a grove, for the purpose of meditation and prayer. The Jews were much in the habit of selecting such places for private devotion, and in such scenes of stillness and retirement there is something especially favorable for meditation and prayer. Our Saviour also worshipped in such places. Compare Joh 18:2; Luk 6:12. In that place of retirement it is not improbable that Nathanael was engaged in private devotion.

I saw thee - It is clear, from the narrative, that Jesus did not mean to say that he was bodily present with Nathanael and saw him; but he knew his thoughts, his desires, his secret feelings and wishes. In this sense Nathanael understood him. We may learn:

1. That Jesus sees what is done in secret, and is therefore divine.

2. That he sees us when we little think of it.

3. That he sees us especially in our private devotions, hears our prayers, and marks our meditations. And,

4. That he judges of our character chiefly by our private devotions. Those are secret; the world sees them not; and in our closets we show what we are. How does it become us, therefore, that our secret prayers and meditations should be without “guile” and hypocrisy, and such as Jesus will approve!

Btw there is an interesting post about Nazareth.

Much we don't understand about this...but the Knowledge of the Roman garrison, and Nathanial's statement to Andrew might reflect on why Jesus said he had on guile...deception allowed in his life.
