Bible Notes Online - Ezekiel 21 - ESV
Commentary

v1-2: Ezekiel's face set towards and against Jerusalem, the centre of religion in Israel.

v3: The sword of Babylon, "my sword." By this both righteous and wicked will be killed.

v4: From south to north, see 20.47, a thorough judgment, burning through the land. It is shocking that the righteous are judged along with the wicked: ‘because of the dry wood, the green wood is burned’ (proverb from Tigrigna people, Eritrea).

v5: The events will be clearly seen as from the Lord.

v6: Groaning with a bitter heart; Ezekiel felt deeply the suffering of his people.

v7: The judgment is coming, and will be brought to pass. God has spoken, and His word must be fulfilled; judgment could not be averted.

We know that, soon after these words, Jerusalem was finally defeated by the Babylonians.

v8:  A new section, sometimes called, ‘the song of the sword,’ v9-17.

v9-12: The sword of the king of Babylon. The people still thought that Judah would remain, her sceptre prevailing over Babylon, the sword despise every such stick, v10, bringing easy victory for Babylon. Since the people genuinely expected God to give them victory, the defeat and exile was devastating. The sword was sent by God against "my people." Ezekiel cried out, and wailed, and beat his breast, as he entered into the sorrow of His people.

v13-17: Judah was tested as well as judged. This required repeated attacks from Babylon, as in 2 Kings 24.1,10-16; 25.1-21. Eventually, through judgment, God's wrath subsided.

v18-23: A further illustration, perhaps marked out on the ground for the people to see. The King of Babylon considered Judah and Ammon alike; perhaps each was as guilty of wrongdoing. See Amos 1.13-15; 2.4-5. The illustration includes a careful detail of Babylonian divination (casting lots, consulting idols, examining the liver).

v24-27: Amongst the various illustrations are clear statements concerning Israel's guilt before God. Ezekiel continues his poetic form, “A ruin, a ruin;” see v9, 28, “A sword, a sword.”

However, the prophet also speaks of future restoration, when the ruin of the nation will be restored, when Christ comes to the land of Israel.

v28-32: The defeat of Ammon, suffering the same sharpened and polished sword as Jerusalem (v10). They too had been given false promises of escape, but the arrival of the sword of Babylon would give the lie to those promises. Ammon had insulted Jerusalem, and would suffer judgment as a result.

Contrast Jer 49.6, where he speaks of a future for Ammon.
