John Gill Commentary 1 Chronicles 16:35

"And say ye, Save us, O God of our salvation, And gather us together and deliver us from the nations, To give thanks unto thy holy name, And to triumph in thy praise." — 1 Chronicles 16:35 (ASV)

Ver. 35,36. And say you, save us, O God of our salvation The author of temporal, spiritual, and eternal salvation; the words are a direction to the singers, and those that sung with them, to express the prayer and doxology in the next verse, which both are the same with (Psalms 106:47Psalms 106:48) . (See Gill on Psalms 106:47) (See Gill on Psalms 106:48); which David directed by a spirit of prophecy, foreseeing the people of Israel would be in captivity among the Heathens; though some think these were added by Ezra; for though there was in his time a return from the captivity, yet many still remained in it.
