ZEDEKIAH'S REIGN. (2-Chronicles 36:11-21)
Zedekiah--Nebuchadnezzar appointed him. His name, originally Mattaniah, was, according to the custom of Oriental conquerors, changed into Zedekiah. Though the son of Josiah (1-Chronicles 3:15; Jeremiah 1:2-3; Jeremiah 37:1), he is called the brother of Jehoiachin (2-Chronicles 36:10), that is, according to the latitude of Hebrew style in words expressing affinity, his relative or kinsman (see 2-Kings 24:18; 2Ki. 25:1-21).

The reign of Zedekiah; the destruction of Jerusalem, and Judah carried away into exile. Cf. 2 Kings 24:18-25:21. - Zedekiah, made king at the age of twenty-one years, reigned eleven years, and filled up the measure of sins, so that the Lord was compelled to give the kingdom of Judah up to destruction by the Chaldeans. To that Zedekiah brought it by the two main sins of his evil reign, - namely, by not humbling himself before the prophet Jeremiah, from the mouth of Jahve (2-Chronicles 36:12); and by rebelling against King Nebuchadnezzar, who had caused him to swear by God, and by so hardening his neck (being stiff-necked), and making stout his heart, that he did not return to Jahve the God of Israel. Zedekiah's stiffness of neck and hardness of heart showed itself in his refusing to hearken to the words which Jeremiah spoke to him from the mouth of God, and his breaking the oath he had sworn to Nebuchadnezzar by God. The words, "he humbled himself not before Jeremiah," recall Jeremiah 37:2, and the events narrated in Jeremiah 37 and 38, and 21:4-22:9, which show how the chief of the people ill-treated the prophet because of his prophecies, while Zedekiah was too weak and languid to protect him against them. The rebellion against Nebuchadnezzar, to whom he had sworn a vassal's oath of fidelity, is mentioned in 2-Kings 24:20, and Ezekiel 17:13. also, as a great crime on the part of Zedekiah and the chief of the people; see the commentary on both passages. In consequence of this rebellion, Nebuchadnezzar marched against Judah with a powerful army; and after the capture of the fenced cities of the land, he advanced to the siege of Jerusalem, which ended in its capture and destruction, 2-Kings 25:1-10. Without further noticing these results of this breach of faith, the author of the Chronicle proceeds to depict the sins of the king and of the people. In the first place, he again brings forward, in 2-Chronicles 36:13, the stiffness of neck and obduracy of the king, which manifested itself in the acts just mentioned: he made hard his neck, etc. Bertheau would interpret the words וגו ויּקשׁ, according to Deuteronomy 2:30, thus: "Then did God make him stiff-necked and hardened his heart; so that he did not return to Jahve the God of Israel, notwithstanding the exhortations of the prophets." But although hardening is not seldom represented as inflicted by God, there is here no ground for supposing that with ויּקשׁ the subject is changed, while the bringing forward of the hardening as an act of God does not at all suit the context. And, moreover, ערף הקשׁה, making hard the neck, is nowhere ascribed to God, it is only said of men; cf. 2-Kings 17:14; Deuteronomy 10:16; Jeremiah 19:15, etc. To God only את־לב הקשׁה or את־רוּח is attributed, Exodus 7:3; Deuteronomy 2:30.
