John Gill Commentary Psalms 106:47

"Save us, O Jehovah our God, And gather us from among the nations, To give thanks unto thy holy name, And to triumph in thy praise." — Psalms 106:47 (ASV)

Save us, O Lord our God Here the psalmist represents the people in captivity, and represents them as praying for deliverance; as well knowing that none but God could save them: and a prayer of this nature, with respect to spiritual salvation, supposes danger, and a sense of it; that they are not able to save themselves, nor any creature able to save them; only the Lord, who is both willing and able; and of this kind is the prayer of faith.

And gather us from among the Heathen ; in Babylon, and other countries; (See Gill on Psalms 106:1).

To give thanks unto thy holy name ; bring us out of captivity to our own land, to Jerusalem, to the temple there to give thanks to thy holy name for the merciful deliverance of us; see (Psalms 122:4) .

And to triumph in thy praise ; in thy salvation, in thy wondrous works, worthy of praise; or while praising thee: the word signifies to glory therein; and such who are sensible of the mercies they receive from the Lord will make their boast of him and them, and glory; see (Psalms 34:1–3) .
