9:23-26 In this world of sin and sorrow, ending soon in death and judgement, how foolish for men to glory in their knowledge, health, strength, riches, or in any thing which leaves them under the dominion of sin and the wrath of God! and of which an account must hereafter be rendered; it will but increase their misery. Those are the true Israel who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh. Let us prize the distinction which comes from God, and will last for ever. Let us seek it diligently.
26. Egypt—put first to degrade Judah, who, though in privileges above the Gentiles, by unfaithfulness sank below them. Egypt, too, was the power in which the Jews were so prone to trust, and by whose instigation they, as well as the other peoples specified, revolted from Babylon.
in the utmost corners—rather, "having the hair shaven (or clipped) in angles," that is, having the beard on the cheek narrowed or cut: a Canaanitish custom, forbidden to the Israelites (Le 19:27; 21:5). The Arabs are hereby referred to (compare Jer 25:23; 49:32), as the words in apposition show, "that dwell in the wilderness."
uncircumcised … uncircumcised in the heart—The addition of "in the heart" in Israel's case marks its greater guilt in proportion to its greater privileges, as compared with the rest.
