Why did King Solomon seek to redefine marriage as a union between 1 man and 700 wives. And 300 concubines?

Answer 1

Well the Bible tells us why. Cause the poor man had a weakness for the ladies. It didn't work out too well for him, either, if I recall.

Answer 2

Solomon thoroughly knew and understood God’s Law. He would doubtless have taken special interest in the instructions that were set out for those who became kings in Israel. Among those instructions was one that stated: “[The king] should also not multiply wives for himself, that his heart may not turn aside.” (Deuteronomy 17:14, 17) Despite that clear direction, Solomon acquired seven hundred wives and three hundred concubines. Many of these women worshiped foreign gods. We do not know why Solomon took so many wives, nor do we know how he justified doing so. What we do know is that he failed to obey God’s clear direction. The outcome was precisely what Jehovah had warned it would be. We read: “[Solomon’s] wives gradually . . . inclined his heart to follow other gods.” (1 Kings 11:3, 4) “Gradually”—but surely—his godly wisdom faded. He drifted. In time, Solomon’s desire to please his pagan wives displaced his desire to obey and please God. How tragic, for Solomon was the one who earlier wrote the words: “Be wise, my son, and make my heart rejoice, that I may make a reply to him that is taunting me”!—Proverbs 27:11.

Answer 3

because the YHWH did not sanitize the Bible, unlike other religions. YHWH allow the full depravity of men to be exhibited, as sins for instruction to others. It was Solomon being the chief source of idolatry that destroy the united kingdom of Israel.

Answer 4

That was none of God's doings. God actually took away all of Solomon's blessings because his women took Solomon away from God.

Answer 5

Because he was the king and he could.
