Verse 2: And he had two wives; the name of the one was Hannah, and the name of the other Peninnah: and Peninnah had children, but Hannah had no children.
[He had two wives] After the custom of that age. Peninnah appears to have been taken to wife, not out of lust, but for offspring; because Hannah was barren; just as Abraham took Hagar, etc. (Lapide, Sanchez). It was bigamy, yet it is not reprehended, with God formerly overlooking such (Drusius).
He had two wives; as divers other good men had in those ages. And it is probable that he took a second wife, to wit, Peninnah, because Hannah, who being first named seems to have been his first wife, was barren.
