As the Box was being brought into the city, Michal, Saul's daughter, looked out of the window and saw King David dancing and jumping around in the sacred dance, and she was disgusted with him.
This was how the birth of Jesus Christ took place. His mother Mary was engaged to Joseph, but before they were married, she found out that she was going to have a baby by the Holy Spirit.
and Saul ordered them to tell David: “All the king wants from you as payment for the bride are the foreskins of a hundred dead Philistines, as revenge on his enemies.” (This was how Saul planned to have David killed by the Philistines.)
David and his men went and killed two hundred Philistines. He took their foreskins to the king and counted them all out to him, so that he might become his son-in-law. So Saul had to give his daughter Michal in marriage to David.
