Ruth 3:9

9. Spread… thy skirt over thine handmaid Literally, spread thy wing. The meaning is, Take me into the protection and intimacy of the marriage relation. The figure, taken originally from birds that cover their young with their wings for protection, is appropriately used of the marriage state. Thus in Ezekiel 16:8, Jehovah represents himself as spreading his wing over Jerusalem in the time of love, and thus taking her to wife. Also in Deuteronomy 22:30; Deuteronomy 27:20, a man guilty of incest is represented as one that uncovereth his father’s wing, or skirt, because he meddles with that which is closed and legally sealed to all but the married pair.

Thou art a near kinsman A goel, from whom I have a legal right to claim this relation.
