And Mesha king of Moab was a sheep master
With which his country abounded; he kept great numbers of them, and shepherds to take care of them; he traded in them, and got great riches by them; his substance chiefly consisted in them:
and rendered unto the king of Israel:
either as a present, or as an annual tribute:
an hundred thousand lambs, and an hundred thousand rams, with the wool;
that is, upon them, unshorn, and so the more valuable; and it was usual for tributary nations to pay their tribute to those to whom they were subject in such commodities which they most abounded with; so the Cappadocians, as Strabo F3 relates, used to pay, as a tribute to the Persians, every year, 1500 horses and 2000 mules, and five myriads of sheep, or 50,000; and formerly, Pliny F4 says, the only tribute was from the pastures.
