#1: Who was the first in the OT to have more than 1 wife simultaneously? (this is probably easy - was it Jacob with Leah and Rachel or was it before then?) #2: When and why did the Jewish custom of having more than 1 wife at the same time stop so that in the NT there was only 1 wife again? Am wondering about the history, not whether it is right or wrong. Although, I may comment later when I'm not so tired. But does anyone know the Jewish/Christian history about question #1 and #2? Thanks.
