Ye [are] my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I [am] he: before me there was no God formed, neither shall there be after me.
Ver. 10. Ye are my witnesses.] He taketh to witness of this great truth in question, not heaven, earth, sea, &c., but his people, among whom he had given in all ages so many clear arguments and experiments of his divinity, his oracles and miracles for instance.
And my servant whom I have chosen,] i.e., Christ, saith the Chaldee paraphrast; the prophet Isaiah, say others; or, which is more likely, Cyrus, who is called God's elect servant, Isa 42:1 and his testimony concerning God is to be read in Ezra 1:3, "The Lord God of Israel he is God." Every true believer doth as much, if not more; for "He that believeth hath set to his seal that God is true," Joh 3:33 hath given him a testimonial, such as is that in Deuteronomy 32:4, "A God of truth, and without iniquity, just and right is he." Such a sealer was Abraham, Rom 4:20 and "such honour have all his saints."
That ye may know and believe and understand.] That ye may have a "full assurance of knowledge," as Luk 1:4 and a "full assurance of faith." Heb 10:22
