Psalms 135:4,5 - Joseph Benson’s Commentary on the Old and New Testaments

For the Lord hath chosen Jacob, &c. Here we have a third reason why the Israelites should praise the Lord, namely, “the circumstance of their having been selected from among the nations to be his church, to receive the law and the promises, to have his presence residing in the midst of them, and to be the guardians of the true faith and worship.” For I know that the Lord is great, &c. Here he assigns a fourth reason for their praising God, “his superiority over the gods of the heathen, and, consequently, over those who worshipped them; from whence followed this comfortable inference, that he was able to protect and to defend his people against every enemy.” Horne.
