1 Samuel 23:23

(23) Throughout all the thousands of Judah.—The “thousands” (Heb., alaphim), as we learn from Numbers 1:16; Numbers 10:4, were the greater tribal divisions. Judah was especially mentioned by Saul as being “the tribe of David,” and where he found probably the larger number of his adherents. It was too, from its importance, the typical tribe, certainly in the southern part of Canaan.
