Albert Barnes Commentary Ruth 1:14

"And they lifted up their voice, and wept again: and Orpah kissed her mother-in-law, but Ruth clave unto her." — Ruth 1:14 (ASV)

The kiss at parting, as well as at meeting, is the customary friendly and respectful salutation in the East. The difference between mere kindness of manner and self-sacrificing love is most vividly depicted in the words and conduct of the two women. Ruth’s determination is steadfast to cast in her lot with the people of the Lord (compare the marginal references and Matthew 15:22-28).
