Psalms 116:13

I will take the cup of salvation - Literally, The cup of salvation, or deliverance, will I lift up. Alluding to the action in taking the cup of blessing among the Jews, which, when the person or master of the family lifted up, he said these words, "Blessed be the Lord, the Maker of the world, who has created the fruit of the vine!"

But it may probably allude to the libation-offering, Numbers 28:7; for the three last verses seem to intimate that the psalmist was now at the temple, offering the meat-offering, drink-offering, and sacrifices to the Lord. Cup is often used by the Hebrews to denote plenty or abundance. So, the cup of trembling, an abundance of misery; the cup of salvation, an abundance of happiness.

And call upon the name of the Lord - I will invoke his name, that I may get more of the same blessings; for the only return that God requires is, that we ask for more. Who is like God? One reason why we should never more come to a fellow-mortal for a favor is, we have received so many already. A strong reason why we should claim the utmost salvation of God is, because we are already so much in debt to his mercy. Now this is the only way we have of discharging our debts to God; and yet, strange to tell, every such attempt to discharge the debt only serves to increase it! Yet, notwithstanding, the debtor and creditor are represented as both pleased, both profited, and both happy in each other! Reader, pray to him, invoke his name; receive the cup - accept the abundance of salvation which he has provided thee, that thou mayest love and serve him with a perfect heart.

I will take the cup of salvation - Compare the notes at Psalm 11:6. The "cup of salvation" means the cup by which his sense of the greatness of the salvation might be expressed - the cup of thanksgiving. Compare the notes at 1 Corinthians 10:16. The reference seems to be to a custom in festivals of drinking a cup of wine as a special expression of thanks or of obligation. The act would be more solemn, and the truth more deeply impressed on the mind, when accompanied by some religious rite - some ceremonial, as in the Lord's Supper, expressly designed to call the mercy of God to remembrance.

And call upon the name of the Lord - Engage in a solemn act of devotion; make it a matter of special ceremony or observance to call the mercy of God to remembrance. This was one way of rendering to the Lord a return for the benefits received at his hands; as it is now. Christians do this at the table of the Lord - in the observance of the Lord's Supper.
