This is the number of the people whom Nebuchadnezzar carried away captive: in the seventh year, 3,023 Judeans;
We have here a very melancholy account, 1. Of the slaughter of some great men, in cold blood, at Riblah, seventy-two in number (according to the number of the elders of Israel, Num 11:24, Num 11:25), so they are computed, Kg2 25:18, Kg2 25:19. We read there of five out of the temple, two out of the city, five out of the court, and sixty out of the country.
Commenting on Jeremiah 52:24-30
In the eighteenth year of Nebuchadnezzar,.... Said to be the nineteenth, Jer 52:12; it was at the end of the eighteenth, and the beginning of the nineteenth, as Kimchi; or this was before the taking of the city, when he raised the siege, and departed to meet the king of Egypt, at which time he might carry captive many, as here said: he carried away...

Also in 2Ki. 24:1-20, ten thousand (Jer 52:14), and seven thousand men of might, and a thousand craftsmen (Jer 52:16), are said to have been carried away, But here three thousand twenty-three.
