Albert Barnes Commentary Ruth 1:8

"And Naomi said unto her two daughters-in-law, Go, return each of you to her mother`s house: Jehovah deal kindly with you, as ye have dealt with the dead, and with me." — Ruth 1:8 (ASV)

Accompanying their mother-in-law to the borders of their own land would probably be an act of Eastern courtesy. Naomi with no less courtesy presses them to return. The mention of the mother’s house, which the separation of the women’s house or tent from that of the men facilitates, is natural in her mouth, and has more tenderness in it than father’s house would have had; it does not imply the death of their fathers (Ruth 2:11).
