Shâlak (שָׁלַךְ, Strong's #7993), “to throw, fling, cast, overthrow.” This root seems to be used primarily in Hebrew, including modern Hebrew. Shâlak is found 125 times in the Hebrew Bible. Its first use in the Old Testament is in Gen. 21:15, which says that Hagar “cast the child [Ishmael] under one of the shrubs.”The word is used to describe the “throwing” or “casting” of anything tangible: Moses “threw” a tree into water to sweeten it (Exod. 15:25); Aaron claimed he “threw” gold into the fire and a golden calf walked out (Exod. 32:24). Trees “shed” or “cast off” wilted blossoms (Job 15:33).
Shâlak indicates “rejection” in Lam. 2:1: “How hath the Lord … cast down from heaven unto the earth the beauty of Israel.…” The word is used figuratively in Ps. 55:22: “Cast thy burden upon the Lord.…”
