As the Ark of the Lord was carried into the City of David, Saul's daughter Michal looked down from a window. She watched King David leaping and dancing before the Lord, and she really loathed him.
This is how the birth of Jesus the Messiah happened. His mother, Mary, was engaged to Joseph, but before they slept together she became pregnant by the Holy Spirit.
Saul told them, “Tell David, ‘The only dowry the king wants for the bride is one hundred foreskins of dead Philistines as a way of taking revenge on his enemies.’” Saul's plan was to have David be killed by the Philistines.
David set off with his men and killed two hundred Philistines, and brought back their foreskins. They counted them all out before the king so that David could become the king's son-in-law. So Saul gave him his daughter Michal in marriage.
