Matthew Poole and continuators on Psalms 96:7

7 Give unto the LORD, O ye kindreds of the people : give unto the LORD glory and strength.

Or, O ye families of the people of the World. And the word families may be understood either 1. strictly and properly; and so it may be intimated that this great blessing of salvation by Christ should not be imparted to whole Nations, but onely to some persons taken out of every people and nation, as it is expressed, Revel. 5. 9. or 2. more largely for nations, as it is taken Gen. 12. 3. Ier. 25. 9. Zech. 14. 18. and so it may be implied that not onely some few of the Heathen people should be brought to the acknowledgment and worship of the true God, as was usual in the times of the Old Testament, but that whole Nations should come in to the Church of God together.

Ascribe to him or acknowledge to be in him.
