Psalm 54:4-6 Revised Standard Version Catholic Edition (RSVCE)
4 Behold, God is my helper;
the Lord is the upholder of my life.
5 He will requite my enemies with evil;
in thy faithfulness put an end to them.
6 With a freewill offering I will sacrifice to thee;
I will give thanks to thy name, O Lord, for it is good.
