1 Sam 18:27

וַיָּ֨קָם דָּוִ֜ד וַיֵּ֣לֶךְ ה֣וּא וַאֲנָשָׁ֗יו וַיַּ֣ךְ בַּפְּלִשְׁתִּים֮ מָאתַ֣יִם אִישׁ֒ וַיָּבֵ֤א דָוִד֙ אֶת־עָרְלֹ֣תֵיהֶ֔ם וַיְמַלְא֣וּם לַמֶּ֔לֶךְ לְהִתְחַתֵּ֖ן בַּמֶּ֑לֶךְ וַיִּתֶּן־ל֥וֹ שָׁא֛וּל אֶת־מִיכַ֥ל בִּתּ֖וֹ לְאִשָּֽׁה׃ ס

David and his men went out and killed two hundred Philistines. He brought their foreskins and presented them as payment in full to become the king’s son-in-law. Then Saul gave his daughter Michal to David in marriage.
