David sent messengers to Ish-bosheth son of Saul with this demand: ¹  “Give me my wife Michal whom I acquired ²  for a hundred Philistine foreskins.”

So Joshua made flint knives and circumcised the Israelites on the Hill of the Foreskins. ¹ 

You must circumcise the flesh of your foreskins. This will be a reminder ¹  of the covenant between me and you.

Saul replied, “Here is what you should say to David: ‘There is nothing that the king wants as a price for the bride except a hundred Philistine foreskins, so that he can be avenged of his ¹  enemies.’” (Now Saul was thinking that he could kill David by the hand of the Philistines.)

when David, along with his men, went out ¹  and struck down two hundred Philistine men. David brought their foreskins and presented all of them to the king so he could become the king’s son-in-law. Saul then gave him his daughter Michal in marriage.

Abraham took his son Ishmael and every male in his household (whether born in his house or bought with money) ¹  and circumcised them ²  on that very same day, just as God had told him to do.

Just as ritual circumcision cuts away the foreskin as an external symbol of dedicated covenant commitment, you must genuinely dedicate yourselves to the Lord and get rid of everything that hinders your commitment to me, ¹  people of Judah and inhabitants of Jerusalem. If you do not, ²  my anger will blaze up like a flaming fire against you that no one will be able to extinguish. That will happen because of the evil you have done.”
