Why does the Bible echo itself so much....

One of the things I've noticed over the years of reading my 10 Lists, 10 Chapters readings in the KJV is how words and themes echo through out scripture. I take this as not random, but more of what I describe as the symphonic nature of scripture...God's word all playing in concert to the same master score.

Earlier today I read...about the origin of Moab, and here below the prophetic text about them over a thousand of years later

Gen 19:36  Thus were both the daughters of Lot with child by their father.

Gen 19:37  And the firstborn bare a son, and called his name Moab: the same is the father of the Moabites unto this day.

Gen 19:38  And the younger, she also bare a son, and called his name Benammi: the same is the father of the children of Ammon unto this day.

Isa 16:1  Send ye the lamb to the ruler of the land from Sela to the wilderness, unto the mount of the daughter of Zion.

Isa 16:2  For it shall be, that, as a wandering bird cast out of the nest, so the daughters of Moab shall be at the fords of Arnon.

Isa 16:3  Take counsel, execute judgment; make thy shadow as the night in the midst of the noonday; hide the outcasts; bewray not him that wandereth.

Isa 16:4  Let mine outcasts dwell with thee, Moab; be thou a covert to them from the face of the spoiler: for the extortioner is at an end, the spoiler ceaseth, the oppressors are consumed out of the land.

Isa 16:5  And in mercy shall the throne be established: and he shall sit upon it in truth in the tabernacle of David, judging, and seeking judgment, and hasting righteousness.

Isa 16:6  We have heard of the pride of Moab; he is very proud: even of his haughtiness, and his pride, and his wrath: but his lies shall not be so.

Isa 16:7  Therefore shall Moab howl for Moab, every one shall howl: for the foundations of Kirhareseth shall ye mourn; surely they are stricken.

Isa 16:8  For the fields of Heshbon languish, and the vine of Sibmah: the lords of the heathen have broken down the principal plants thereof, they are come even unto Jazer, they wandered through the wilderness: her branches are stretched out, they are gone over the sea.

Isa 16:9  Therefore I will bewail with the weeping of Jazer the vine of Sibmah: I will water thee with my tears, O Heshbon, and Elealeh: for the shouting for thy summer fruits and for thy harvest is fallen.

Isa 16:10  And gladness is taken away, and joy out of the plentiful field; and in the vineyards there shall be no singing, neither shall there be shouting: the treaders shall tread out no wine in their presses; I have made their vintage shouting to cease.

Isa 16:11  Wherefore my bowels shall sound like an harp for Moab, and mine inward parts for Kirharesh.

Isa 16:12  And it shall come to pass, when it is seen that Moab is weary on the high place, that he shall come to his sanctuary to pray; but he shall not prevail.

Isa 16:13  This is the word that the LORD hath spoken concerning Moab since that time.

Isa 16:14  But now the LORD hath spoken, saying, Within three years, as the years of an hireling, and the glory of Moab shall be contemned, with all that great multitude; and the remnant shall be very small andfeeble.
