I will take the cup of salvation
Or "salvations" F14; not the eucharistic cup, or the cup in the Lord's supper, which the apostle calls "the cup of blessing", ( 1 Corinthians 10:16 ) ; though some so think, and that the psalmist represents the saints under the Gospel dispensation; nor the cup of afflictions or martyrdom for the sake of Christ; being willing, under a sense of mercies received, to bear or suffer anything for his sake he should call him to; as knowing it would be a token to him of salvation, and work for his good: but rather an offering of praise for temporal salvation, and for spiritual and eternal salvation; in allusion to a master of a family, who at the close of a feast or meal, used to take up a cup in his hands, and give thanks; see ( Matthew 26:27 ) ;
and call upon the name of the Lord;
invocation of the name of the Lord takes in all worship and service of him, public and private, external and internal; and particularly prayer, which is calling upon the Lord in the name of Christ, with faith and fervency, in sincerity and truth: and the sense of the psalmist is, that he would not only give thanks for the mercies he had received, but continue to pray to God for more; and this was all the return he was capable of making.
