Heb goel, from root meaning to redeem. The goel among the Hebrews was the nearest male blood relation alive. Certain important obligations devolved upon him toward his next of kin. (1.) If any one from poverty was unable to redeem his inheritance, it was the duty of the kinsman to redeem it (Le 25:25,28; Ru 3:9,12). He was also required to redeem his relation who had sold himself into slavery (Le 25:48-49).

God is the Goel of his people because he redeems them (Ex 6:6; Isa 43:1; 41:14; 44:6,22; 48:20; Ps 103:4; Job 19:25, etc.).

(2.) The goel also was the avenger (q.v.) of blood (Nu 35:21) in the case of the murder of the next of kin.
