Yigal (יִגְאָל) is a theophoric Hebrew name meaning "He will redeem\” or "God redeems\”, derived from the crucial root gaal (to redeem as kinsman-redeemer). It appears as the name of several men in the Hebrew Bible, most notably one of the twelve spies sent by Moses (Numbers 13:7) and one of David's mighty warriors (2 Samuel 23:36).
Names carrying the root gaal are declarations of theological confidence — the bearer's very name proclaims that Yahweh is a Redeemer who acts on behalf of His people. The kinsman-redeemer (goel) concept is one of the richest in the OT: a near relative with both the right and responsibility to redeem a family member from slavery, poverty, or death.
That Moses sent a man named "God Redeems" (Yigal) as a spy into the land of promise is a quiet irony of Numbers 13 — even the man sent to scout the land bore a name that declared the conclusion before the mission began. The redeemed shall inherit the land. The NT fulfillment is explicit: Christ as the ultimate goel, redeeming humanity from the slavery of sin at the cost of His own blood (Galatians 3:13; Ruth 4 as type).
