30:18 Yahweh promised to restore Israel's tribal fortunes (cf. Num. 24:5-6), to have compassion on His peoples' towns and homes, and to rebuild Jerusalem and the royal palace there.
30:19 Thanksgiving and merrymaking would mark the people. The Lord would increase their numbers and honor them.
30:20 Their children would be secure and happy, as they were before God judged the people. The people as a whole would again be stable, and the Lord would punish their oppressors.
30:21 Their leader would be one of them, not a foreign ruler who imposed his rule on them. The Lord would draw this leader to Himself, would call Him to His place of service. Approaching Yahweh was a priestly prerogative, so this verse may hint at the future ruler's priestly as well as His kingly function (cf. Ps. 110:4; Zech. 6:13).
"The ruler will need no mediator. Thus he will be greater than even David and Solomon. Like Melchizedek he will have a dual role. No man can take to himself the office of priesthood (cf. Heb 5:4). In fact, it was dangerous for even a king to do so (cf. Jeroboam in 1 Kings 12:26-33; 13:1-6; and Uzziah in 2 Chron 26:16-20). . . . Here is a reiteration of the promise to restore the Davidic line (cf. v. 9). . . . The Targum, though interpretative, is correct in its rendering Messiah shall be revealed to them out of their own midst.'"399
30:22 Israel and Yahweh would again be in covenant relationship as people and God (cf. 7:23; 11:4; Gen. 17:7; Exod. 6:7; Lev. 26:12; Deut. 7:26; Isa. 35; Ezek. 36:28).
