2 Kings 3:4 - Joseph Benson’s Commentary on the Old and New Testaments

Mesha, king of Moab, was a sheep-master The riches, not only of private men, but also of kings, in ancient times, consisted much in sheep and cattle. And this king of Moab had abundance of them, which imboldened and enabled him to rebel against his sovereign. And rendered to the king of Israel a hundred thousand lambs, &c. This was a prodigious number, and as they were rendered unshorn, they were the more valuable. But we are to consider that these countries abounded with sheep; insomuch that Solomon offered one hundred and twenty thousand at the dedication of the temple, 2 Chronicles 7:5; and the Reubenites drove from the Hagarenes one hundred and fifty thousand, 1 Chronicles 5:7.
