Psalms 47:3 - Matthew Poole's English Annotations on the Holy Bible

Or, he shall lead like sheep; or, bring into the fold; as divers render the word, by comparing Isaiah 5:17 Micah 2:12. He seems to speak of such a subjugation of them, as was for the good of the people subdued, because this is matter of rejoicing to them, Psalms 47:1; which is true both of these people whom David subdued, who thereby had opportunities, obligations, and encouragements to own and worship the true God, which was the only way to their true and lasting happiness; and especially of those Gentiles who were subdued to Christ by the preaching of the gospel. The Gentile converts were in some sort brought under the Jews, because they were subjected to Christ, and to his apostles, and to the primitive church, which were Jews. Or the psalmist may speak this in the name of the whole church, which then were Israelites only, but afterwards were madeup of Jews and Gentiles, unto which all particular believers were to submit themselves in and for the Lord.
