I concede th there is no direct condemnation of those n the bible who had multiple wives and concubines. However the Matthew passage is important because it confirms the creation ordinance. Ie Jesus confirmed that was how it should be. We do find that Deuteronomy looking forward to kingship forbad kings to multiply wives, Jesus taught that Moses law allowed divorce .....for the hardness of your hearts...ie a less than perfect allowance , and the thought is that the same pertains with this discussion, but again, I concede is not directly spelt out. Gotta go....
