Thousands
In Israelite tribal organization, the "thousand" (Hebrew eleph) functioned as a subdivision of the tribe used for military mustering, census-taking, and judicial organization. Moses appointed leaders of thousands, hundreds, fifties, and tens to share the burden of judgment (Ex. 18:21). Military units were organized by thousands with their commanders (Num. 31:14; 1 Sam. 8:12).
The large numbers in the Mosaic census lists (Num. 1; 26) have generated extensive scholarly discussion: some interpreters read eleph as a clan or unit designation rather than a literal count of one thousand, which would reduce the total population figures substantially. The term also appears in the blessings on Israel (Deut. 1:11; Ps. 68:17) and in the prophecy of Bethlehem as "little among the thousands of Judah" (Mic. 5:2), where it clearly means a tribal subdivision rather than a precise number.
