A lot of things in the Bible are for us to discern. For instance it tells us that Solomon had many wives and concubines, but doesn’t tell us whether or not that was a good thing. Today we assume it’s a bad thing. In fact David and Solomon were pretty rotten guys in a lot of ways by modern Christian standards.
“it tells us that Solomon had many wives and concubines, but doesnt tell us whether or not that was a good thing.”
Actually Scripture ordains one man/one woman marriage from the beginning, and requires that elders be the husband of one wife. There is no allowance for concubines in the law, either.
All laws regarding marriage are referencing one man and one woman.
