According to the author of 1 Kings, this story is about two women who both say a baby is theirs and they are talking to the king to help decide who is telling the truth. It's a story that shows how wise the king is at figuring things out.
1 Kings 3:22: And the other woman said, Nay; but the living [is] my son, and the dead [is] thy son. And this said, No; but the dead [is] thy son, and the living [is] my son. Thus they spake before the king.
This verse states that lying lips are an abomination to the Lord, while 1 Kings 3:22 involves a woman falsely claiming the living child as her own.
Proverbs 12:22: Lying lips [are] abomination to the LORD: but they that deal truly [are] his delight.
