Joshua 13:3

From Sihor, which [is] before Egypt, even unto the borders of Ekron northward, [which] is counted to the Canaanite: five lords of the Philistines; the Gazathites, and the Ashdothites, the Eshkalonites, the Gittites, and the Ekronites; also the Avites:

Ver. 3. From Sihor.] Or Nile, which hath its name Sihor from blackness, and Nile from muddiness. So much of Egypt as this river watereth, is a black mould, so fruitful, as they do but throw in the seed, and have four rich harvests in less than four months, as travellers tell us.

Also the Avites.] Who, belike, still held part of their old possession. Deu 2:22-23
