If there is nothing "special" about marriage being between one man and one woman; then, what is so special about the number 2?
Once you re-define something, it is open to being re-defined over and over again. The Left always denies the slippery slope; but, a slippery slope is inevitable. Once one group gets to redefine an institution for their agenda, you simply cannot keep out other re-definitions.
Yes, and in each case these plural wives brought them grief and harmed the Kingdom of Israel and the world. Also, by the time the Lord Jesus was on earth, plural marriage was no longer recognized. It actually was never sanctioned by God at all....more or less tolerated at best.
God works in strange ways, thank god for Israel.
