21:18-20 The Lord also commanded Ezekiel to make a representation of two roads coming out of Babylon by which judgment from Yahweh would come. Perhaps he did this by drawing in the dirt or on a tablet. Really there was to be one road leaving Babylon that diverged as it approached Jerusalem, and there was to be a signpost at the fork in the road. One of this road's branches would go to Rabbah, the capital city of the Ammonites to the east of Judah. The other branch would lead to Jerusalem.
21:21-22 When the king of Babylon reached the fork in the road, he used pagan methods to determine which road he should take (cf. Isa. 47:8-15). Belomancy involved writing various names on several arrows, mixing them in a quiver, and then drawing or throwing them out. The arrow chosen indicated the god's selection. Teraphim were household idols that the pagans believed had connections with the spirits of departed ancestors who could communicate with them (necromancy). Hepatoscopy involved inspecting the liver or entrails of a sacrificed animal and making a decision based on its shape, color, or markings.
Both Judah and Ammon had proved to be disloyal vassals; they had both rebelled against Babylon in 593 B.C. The lot fell to go against Jerusalem and to besiege it rather than Rabbah. Obviously the Lord controlled the pagan means that Nebuchadnezzar used to determine what He should do (Prov. 16:33; 21:1; Jer. 27:6).
21:23 Nebuchadnezzar's decision to come against Jerusalem would look like a mistake to the leaders of Israel. It would seem to them that God should have guided him to besiege the Ammonites since they were more wicked. Furthermore Israel's leaders had sworn oaths of allegiance to Yahweh in response to His sworn promises to them. They thought surely He would defend them, but they were wrong. He would allow Nebuchadnezzar to capture them.
21:24-27 The Lord would remember the sins of His people and allow them to suffer conquest (Deut. 28-29). He would allow their destruction because their many sins were open before Him. Even wicked King Zedekiah, the prince of Israel, would be as good as dead when his day of judgment came with the taking of Jerusalem. The Lord would remove the high priest's turban and the king's crown by terminating their offices. Then there would be a reversal of fortunes, the powerful would be humbled and the poor of the land would be the only people allowed to remain in it. Yahweh would make Jerusalem the ultimate ruin.301It would no longer enjoy its former glories until One would come who had a divine right to replace both high priest and king (cf. Ps. 110:2, 4; 72; Isa. 9:6; Jer. 23:5; 33:17; Zech. 6:12-13). God would then give the city into His control (Gen. 49:10). This is a messianic prediction of Jesus Christ's future earthly reign (cf. Heb. 5-7).
