Psalm 116: 12, 16b-17 [Latin]12 What shall I render unto the Lord for all his benefits toward me? 

13 I will take the cup of salvation, and call upon the name of the Lord.

16 Lord, truly I am thy servant; I am thy servant, and the son of thine handmaid: thou hast loosed my bonds.

17 I will offer to thee the sacrifice of thanksgiving, and will call upon the name of the Lord.
