Jehoahaz was twenty and three years old when he began to reign, and he reigned three {a} months in Jerusalem.

(a) Three months after the death of Josiah, Necho came to Jerusalem, and so the plagues began, which Huldah and the prophets forewarned would come on Jerusalem.

Jamieson-Fausset-Brown Bible Commentary

2. he reigned three months in Jerusalem-His possession of sovereign power was of but very brief duration; for Necho determined to follow up the advantage he had gained in Judah; and, deeming it expedient to have a king of his own nomination on the throne of that country, he deposed the popularly elected monarch and placed his brother Eliakim or Jehoiakim on the throne, whom he anticipated to be a mere obsequious vassal. The course of events seems to have been this: on receiving intelligence after the battle of the accession of Jehoahaz to the throne, and perhaps also in consequence of the complaint which Eliakim brought before him in regard to this matter, Necho set out with a part of his forces to Jerusalem, while the remainder of his troops pursued their way at leisure towards Riblah, laid a tribute on the country, raised Eliakim (Jehoiakim) as his vassal to the throne, and on his departure brought Jehoahaz captive with him to Riblah. The old expositors mostly assumed that Necho, after the battle of Megiddo, marched directly against Carchemish, and then on his return came to Jerusalem. The improbability, indeed the impossibility, of his doing so appears from this: Carchemish was from four hundred to five hundred miles from Megiddo, so that within "three months" an army could not possibly make its way thither, conquer the fenced city of Carchemish, and then march back a still greater distance to Jerusalem, and take that city [Keil].

Matthew Henry's Concise Commentary

36:1-21 The ruin of Judah and Jerusalem came on by degrees. The methods God takes to call back sinners by his word, by ministers, by conscience, by providences, are all instances of his compassion toward them, and his unwillingness that any should perish. See here what woful havoc sin makes, and, as we value the comfort and continuance of our earthly blessings, let us keep that worm from the root of them. They had many times ploughed and sowed their land in the seventh year, when it should have rested, and now it lay unploughed and unsown for ten times seven years. God will be no loser in his glory at last, by the disobedience of men. If they refused to let the land rest, God would make it rest. What place, O God, shall thy justice spare, if Jerusalem has perished? If that delight of thine were cut off for wickedness, let us not be high-minded, but fear.

Matthew Henry's Whole Bible Commentary

Chapter 36

We have here, I. A short but sad account of the utter ruin of Judah and Jerusalem within a few years after Josiah's death. 1. The history of it in the unhappy reigns of Jehoahaz for three months (v. 1-4), Jehoiakim (v. 5-8) for eleven years, Jehoiachin three months (v. 9, 10), and Zedekiah eleven years (v. 11). Additions were made to the national guilt, and advances towards the national destruction, in each of those reigns. The destruction was, at length, completed in the slaughter of multitudes (v. 17), the plundering and burning of the temple and all the palaces, the desolation of the city (v. 18, 19), and the captivity of the people that remained (v. 20). 2. Some remarks upon it-that herein sin was punished, Zedekiah's wickedness (v. 12, 13), the idolatry the people were guilty of (v. 14), and their abuse of God's prophets (v. 15, 16). The word of God was herein fulfilled (v. 21). II. The dawning of the day of their deliverance in Cyrus's proclamation (v. 22, 23).

Verses 1-10

The destruction of Judah and Jerusalem is here coming on by degrees. God so ordered it to show that he has no pleasure in the ruin of sinners, but had rather they would turn and live, and therefore gives them both time and inducement to repent and waits to be gracious. The history of these reigns was more largely recorded in the last three chapters of the second of Kings. 1. Jehoahaz was set up by the people (v. 1), but in one quarter of a year was deposed by Pharaoh-necho, and carried a prisoner to Egypt, and the land fined for setting him up, v. 2-4. Of this young prince we hear no more. Had he trodden in the steps of his father's piety he might have reigned long and prospered; but we are told in the Kings that he did evil in the sight of the Lord, and therefore his triumphing was short and his joy but for a moment. 2. Jehoiakim was set up by the king of Egypt, an old enemy to their land, gave what king he pleased to the kingdom and what name he pleased to the king! v. 4. He made Eliakim king, and called him Jehoiakim, in token of his authority over him. Jehoiakim did that which was evil (v. 5), nay, we read of the abominations which he did (v. 8); he was very wild and wicked. Idolatries generally go under the name of abominations. We hear no more of the king of Egypt, but the king of Babylon came up against him (v. 6), seized him, and bound him with a design to carry him to Babylon; but, it seems, he either changed his mind, and suffered him to reign as his vassal, or death released the prisoner before he was carried away. However the best and most valuable vessels of the temple were now carried away and made use of in Nebuchadnezzar's temple in Babylon (v. 7); for, we may suppose, no temple in the world was so richly furnished as that of Jerusalem. The sin of Judah was that they had brought the idols of the heathen into God's temple; and now their punishment was that the vessels of the temple were carried away to the service of the gods of the nations. If men will profane God's institutions by their sins, it is just with God to suffer them to be profaned by their enemies. These were the vessels which the false prophets flattered the people with hopes of the return of, Jer. 27:16. But Jeremiah told them that the rest should go after them (Jer. 27:21, 22), and they did so. But, as the carrying away of these vessels to Babylon began the calamity of Jerusalem, so Belshazzar's daring profanation of them there filled the measure of the iniquity of Babylon; for, when he drank wine in them to the honour of his gods, the handwriting on the wall presented him with his doom, Dan. 5:3, etc. In the reference to the book of the Kings concerning this Jehoiakim mention is made of that which was found in him (v. 8), which seems to be meant of the treachery that was found in him towards the king of Babylon; but some of the Jewish writers understand it of certain private marks or signatures found in his dead body, in honour of his idol, such cuttings as God had forbidden, Lev. 19:28. 3. Jehoiachin, or Jeconiah, the son of Jehoiakim, attempted to reign in his stead, and reigned long enough to show his evil inclination; but, after three months and ten days, the king of Babylon sent and fetched him away captive, with more of the goodly vessels of the temple. He is here said to be eight years old, but in Kings he is said to be eighteen when he began to reign, so that this seems to be a mistake of the transcriber, unless we suppose that his father took him at eight years old to join with him in the government, as some think.
