“They lifted up their voice and wept.” That is, they wept aloud. The CSV says, “they wept loudly,” which gets the sense.
“and Orpah kissed her mother-in-law.” That is, she kissed her to show her love and in saying “good-bye.” We should know that at no time in the text is Orpah criticized by the Author or by anyone else. Orpah had no promise from God that she would be well taken care of in Israel. Besides that, she likely had no real confidence in the goodness of Yahweh, Israel’s God. After all, in the thinking of the time, He was the reason for the famine in Israel and certainly did not protect her husband Chilion from dying. So she did the natural thing and went back to her mother’s house where in all likelihood she remarried.
“Ruth clung to her.” The word “clung” is the same word used in Genesis 2:24 for a man being joined to his wife. The text shows that Ruth’s bond with her mother-in-law was very strong.
