Save us, O Lord - and gather us - These words, says Calmet, are found in the hymn that was sung at the ceremony of bringing the ark to Jerusalem, 1 Chronicles 16; but it is supposed they were added by Ezra or some other prophet: here they are in their natural place. The author of the Psalm begs the Lord to gather the Israelites who were dispersed through different countries; for at the dedication of the second temple, under Nehemiah, (where it is probable this Psalm, with the 105th and the 107th, was sung), there were very few Jews who had as yet returned from their captivity.
Save us, O Lord our God, and gather us from among the heathen - From among the nations. From this it would seem that the psalm was composed when the nation was in captivity, or was dispersed among the nations that were hostile to them. The prayer is, that as God had, in former periods, recovered his people when they were in exile, or were scattered abroad, he would again graciously interpose and bring them to the land of their fathers, where they had been accustomed to worship God.
To give thanks unto thy holy name - Unto thee; a holy God. That we may praise thee in the place where thou art accustomed to be worshipped - in the sanctuary.
And to triumph in thy praise - To exult; to rejoice; to be glad in praising thee - in thy worship.
