The fact that Elkanah, a Levite, was denominated an Ephraimite [ 6 ] is analogous to the designation of a Levite belonging to Judah (Judges 17:7, for example). [ 7 ] According to 1 Samuel 1:1–28, Elkanah had two wives, Peninnah and Hannah. Peninnah had children; Hannah did not. Nonetheless, Elkanah favored Hannah. Jealous, Peninnah reproached Hannah for her lack of children, causing Hannah much heartache.
