Psalms 61:8

So will I sing praise unto thy name for ever. Because my prayer is answered, my song shall be perpetual; because Jesus for ever sits at thy right hand, it shall be acceptable; because I am preserved in him, it shall be grateful. David had given vocal utterance to his prayer by a cry; he will now give expression to his praise by a song: there should be a parallel between our supplications and our thanksgivings. We ought not to leap in prayer, and limp in praise. The vow to celebrate the divine name for ever is no hyperbolical piece of extravagance, but such as grace and glory shall enable us to carry out to the letter. That I may daily perform my vows. To God who adds days to our days we will devote all our days. We vowed perpetual praise, and we desire to render it without intermission. We would worship God de die in diem, going right on as the days roll on. We ask no vacation from this heavenly vocation; we would make no pause in this sacred service. God daily performs his promises, let us daily perform our vows: he keeps his covenant, let us not forget ours. Blessed be the name of the Lord from this time forth, even for evermore.

So will I sing praise unto thy name for evher - For the benefits which I have received, and hope to receive endlessly from thee, I will to all perpetuity praise thee. That I may daily perform my vows - While I live, I shall יום יום yom, yom, “day by day,” each day as it succeeds, render to thee my vows - act according to what I have often purposed, and as often promised. The Chaldee ends remarkably: “Thus I will praise thy name for ever, when I shall perform my vows in the day of the rederaption of Israel; and in the day in which the King Messiah shall be anointed, that he may reign.” The ancient Jews were full of the expectation of the Messiah; the Jews of the present day have given up their hope.

So will I sing praise unto thy name for ever - As the result of this gracious interposition. Compare the notes at Isa 38:20. The meaning is, that he would do this constantly. It would be the regular business of his life. That I may daily perform my vows - The solemn promises which I have made in my exile; the purposes which I have expressed to devote myself to thee. Or, the language may have been used in a more general sense, denoting that, as a religious man, the vows of God were constantly on him, or that he had pledged himself to serve God faithfully and always, and that he could better perform this duty at the tabernacle - in the place consecrated to public worship - than he could in exile. He desired, therefore, to be restored to the sanctuary, that he might keep up the performance of the daily duties of religion without interruption or hindrance. The whole psalm indicates a fervent desire to be engaged in the worship and service of God; a desire to be with Him and to enjoy His favor on earth; a confident hope that he would be permitted to enjoy His presence forever.
