'Psalm' in the Bible

he has fulfilled for us, their descendants, by raising Jesus. As it is written in the second Psalm, "You are my Son. Today I have become your Father.'

In another Psalm he says, "You will not let your Holy One experience decay.'

What, then, does this mean, brothers? When you gather, everyone has a psalm, teaching, revelation, foreign language, or interpretation. Everything must be done for upbuilding.
