4. David says, “I will take the cup of salvation, and call upon the name of the Lord" (Ps 116:13).

The phrase appears to be taken from the custom of the Jews in their thank-offerings, in which a feast was made of the remainder of their sacrifices, when, among other rites, the master of the feast took a cup of wine in his hand, and solemnly blessed God for it, and for the mercies which were then acknowledged, and gave it to all the guests, every one of whom drank in his turn. See CUP. To this custom it is supposed our Lord alludes in the institution of the cup, which is also called "the cup of blessing" (1 Cor 10:16). See PASSOVER. At the family feasts also, and especially that of the Passover, both wine and bread were in this solemn and religious manner distributed, and God was blessed, and his mercies acknowledged. They blessed God for their present refreshment, for their deliverance out of Egypt, for the covenant of circumcision, and for the law given by Moses; they prayed that God would be merciful to his people Israel, that he would send the prophet Elijah, and that he would render them worthy of the kingdom of the Messiah. In the Mosaic Law, the manner of blessing was appointed by the lifting up of hands, and we see that our Lord lifted up his hands and blessed his disciples
