Gôrāl (גּוֹרָל) means lot, portion, allotment, destiny. Casting lots was the primary method of determining God's will in the OT — not gambling but a sacred practice of seeking divine direction.
Proverbs 16:33: 'The lot is cast into the lap, but its every decision is from the LORD.' This is the theology behind casting lots: what appears random to humans is directed by God. Joshua 14:2: the Promised Land was divided 'by lot, as the LORD had commanded.' Leviticus 16:8: on the Day of Atonement, Aaron cast lots for the two goats — one for the LORD, one as the scapegoat. The apostles cast lots to replace Judas (Acts 1:26). In every case, the lot was not chance but divine appointment.
