(1) ’eshkol; compare proper name VALE OF ESHCOL. (which see), from root meaning "to bind together." A cluster or bunch of grapes (Ge 40:10; Nu 13:23; Isa 65:8; So 7:8; Mic 7:1, etc.); a cluster of henna flowers (So 1:14); a cluster of dates (So 7:7). "Their grapes are grapes of gall, their clusters are bitter." (De 32:32).

(2) botrus, "gather the clusters of the vine of the earth" (Re 14:18).

The "cluster of raisins" (tsimmuqim) of 1Sa 25:18; 30:12, should rather be "raisin cakes" or "dried raisins."
