Gilead — Gilead was a country fertile for pastures; upon which account the Reubenites and Gadites, being men whose estate lay in cattle, begged it of Moses for their portion. Lebanon also was a very pleasant place: they were both in the lot of Gad and Manasseh. Perhaps God compares the king of Judah's house to these places, in regard of the height and nobleness of the structure, or for the pleasantness and delightfulness of it.
