Jezreel, Fountain of - (Easton's Bible Dictionary)
Where Saul encamped before the battle of Gilboa (1 Sam. 29:1). In the valley under Zerin there are two considerable springs, one of which, perhaps that here referred to, "flows from under a sort of cavern in the wall of conglomerate rock which here forms the base of Gilboa. The water is excellent; and issuing from crevices in the rocks, it spreads out at once into a fine limpid pool forty or fifty feet in diameter, full of fish" (Robinson). This may be identical with the "well of Harod" (Judg. 7:1; comp. 2 Sam. 23:25), probably the Ain Jalud, i.e., the "spring of Goliath."
