Goel

in Hebrew the participle of the verb "gaal", "to redeem." It is
rendered in the Authorized Version "kinsman," Num. 5:8; Ruth
3:12; 4:1,6,8; "redeemer," Job 19:25; "avenger," Num. 35:12;
Deut. 19:6, etc. The Jewish law gave the right of redeeming and
repurchasing, as well as of avenging blood, to the next
relative, who was accordingly called by this name. (See REDEEMER
