1 In the 9th year of Zedekiah king of Judah, in the 10th month, came Nebuchadrezzar king of Babylon and all his army against Jerusalem, and they besieged it.
Jerusalem was so strong, that the inhabitants firmly believed the enemy could never enter it, consequently by turning away from Yahweh and relying in their own 'strength in sin,' they provoked Yahweh to withdraw His protection, so Jerusalem became as weak as other cities (vv. 1-10; cp. 2Chr. 26:15-16).
Fleeing for his life, Zedekiah was ultimately caught and had his eyes put out, so he was condemned to darkness because he had chosen darkness rather than the clear light of Yahweh's Word. All of those who will not believe Yahweh's words, will never be convinced by this or any other event.
"Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?" (Mark 8:18).
17 But I will deliver thee in that day, saith Yahweh: and thou shalt not be given into the hand of the men of whom thou art afraid.
Amidst the public calamities, on account of his duty and conduct, and his humanity to the prophet, a message is given to assure Ebed-melech of a recompense for his great kindness to Jeremiah.
