Our minds might not grasp it, but polygamy was biblically approved and as such common practice in days gone by.
God did not want his people to take a King. They whined like babies. The Lord said OK you want it? you got it! Here are the rules that go along with your desire that I said you shouldn't yield to.
God did not want slavery. The people wanted it anyway. The Lord said OK, you want it? you got it! Here are the rules that go along with your desire that I didn't ordain.
God wanted ONE man, ONE wife. The men desired more. The Lord said OK, you want it? you got it! Here are the rules that go along with your desire that I didn't ordain.
So yep, there will always be those trying to find technicalities to justify their desires that run counter to what God wants.
