PSALMS:Just like Psalms are the songs of the Redeemed...so too do the Redeemed sing unto God.
Thou art my hiding place; thou shalt preserve me from trouble; thou shalt compass me about with songs of deliverance.
Psalm 32:7
And they sung as it were a new song before the throne,
and before the four beasts, and the elders:
and no man could learn that song
but the hundred and forty and four thousand,
which were redeemed from the earth.
Revelation 14:3
