'Psalm' in the Bible

that God has fulfilled this promise to our children in that He raised up Jesus, as it is also written in the second Psalm, ‘You are My Son; today i have begotten You.’

Therefore He also says in another Psalm, ‘You will not allow Your Holy One to undergo decay.’

What is the outcome then, brethren? When you assemble, each one has a psalm, has a teaching, has a revelation, has a tongue, has an interpretation. Let all things be done for edification.
