Orpah

Orpah was the Moabite wife of Kilion (Chilion), the son of Elimelech and Naomi, and the sister-in-law of Ruth. After the deaths of Elimelech, Mahlon, and Kilion, Naomi urged both daughters-in-law to return to their mothers' houses and remarry in Moab (Ruth 1:8). Orpah kissed her mother-in-law goodbye, wept, and returned to her people and her gods — a decision presented without condemnation in the text. The contrast with Ruth's famous declaration of loyalty (where you go I will go, Ruth 1:16) is the narrative's way of heightening the extraordinary character of Ruth's faithfulness.

Orpah's choice was rational and culturally expected; Ruth's was exceptional. Orpah disappears from the narrative after Ruth 1:14 and is not mentioned again. Rabbinic tradition, elaborated in midrash, sometimes associates Orpah with the Philistine giant Goliath.
