Introducing a new song...but the same conclusion......Psalm 98

I have been listening to God's songs in Psalm...these 3 particularly emphasizing this point of singing.

Psa 95:1    O come, let us sing unto the LORD: let us make a joyful noise to the rock of our salvation.

Psa 95:2    Let us come before his presence with thanksgiving, and make a joyful noise unto him with psalms.

Psa 96:1  O sing unto the LORD a new song: sing unto the LORD, all the earth.

Psa 96:2    Sing unto the LORD, bless his name; shew forth his salvation from day to day.

Psa 98:1    A Psalm. O sing unto the LORD a new song; for he hath done marvellous things: his right hand, and his holy arm, hath gotten him the victory.

Psa 98:2    The LORD hath made known his salvation: his righteousness hath he openly shewed in the sight of the heathen.

Psa 98:3    He hath remembered his mercy and his truth toward the house of Israel: all the ends of the earth have seen the salvation of our God.

Psa 98:4    Make a joyful noise unto the LORD, all the earth: make a loud noise, and rejoice, and sing praise.

Psa 98:5    Sing unto the LORD with the harp; with the harp, and the voice of a psalm.

Psa 98:6    With trumpets and sound of cornet make a joyful noise before the LORD, the King.

Psa 98:7    Let the sea roar, and the fulness thereof; the world, and they that dwell therein.

Psa 98:8    Let the floods clap their hands: let the hills be joyful together

Psa 98:9    Before the LORD; for he cometh to judge the earth: with righteousness shall he judge the world, and the people with equity.

Btw both the two other psalms mentioned above end in the same idea.

Psa 95:10    Forty years long was I grieved with this generation, and said, It is a people that do err in their heart, and they have not known my ways:

Psa 95:11    Unto whom I sware in my wrath that they should not enter into my rest.

Psa 96:13    Before the LORD: for he cometh, for he cometh to judge the earth: he shall judge the world with righteousness, and the people with his truth.
