Judah . . . Israel . . . dwell safely--Compare Jer 33:16, where "Jerusalem" is substituted for "Israel" here. Only Judah, and that only in part, has as yet returned. So far are the Jews from having enjoyed, as yet, the temporal blessings here foretold as the result of Messiah's reign, that their lot has been, for eighteen centuries, worse than ever before. The accomplishment must, therefore, be still future, when both Judah and Israel in their own land shall dwell safely under a Christocracy, far more privileged than even the old theocracy (Jer 32:37; Deu 33:28; Isa. 54:1-17; 60:1-22; Isa 65:17-25; Zac 14:11). shall be called, the Lord--that is, shall be (Isa 9:6) "Jehovah," God's incommunicable name. Though when applied to created things, it expresses only some peculiar connection they have with Jehovah (Gen 22:14; Exo 17:15), yet when applied to Messiah it must express His Godhead manifested in justifying power towards us (Ti1 3:16). our--marks His manhood, which is also implied in His being a Branch raised unto David, whence His human title, "Son of David" (compare Mat 22:42-45). Righteousness--marks His Godhead, for God alone can justify the ungodly (compare Rom 4:5; Isa 45:17, Isa 45:24-25).
