By himself. — Literally, by His soul. Jehovah swears by His life or soul because He could swear by no greater — the eternal “I Am.” (Comp. the formula of Divine asseveration: “As I live, saith the Lord,” which derives illustration from the custom of swearing by the life of a monarch; Genesis 42:15-16.) With the eternal unchangeable being of the Supreme Monarch stands contrasted “the excellency of Jacob,” the false futile glory which Jehovah abhors. In Amos 8:7 the phrase is used for God Himself; not, however, in either passage God’s absolute perfection or objective glory, but the thoughts, sometimes wise, sometimes base, which men have entertained about Him. From the context we infer that the splendid shrine of Samaria, with its unacceptable offerings and calf-worship, is here meant. The reference to the coming destruction of buildings great and small (Amos 6:11) lends colour to this interpretation. (Comp. Amos 6:13.)
