אִם־יוּכַ֞ל לְהִלָּחֵ֤ם אִתִּי֙ וְהִכָּ֔נִי וְהָיִ֥ינוּ לָכֶ֖ם לַעֲבָדִ֑ים וְאִם־אֲנִ֤י אֽוּכַל־לוֹ֙ וְהִכִּיתִ֔יו וִהְיִ֤יתֶם לָ֙נוּ֙ לַעֲבָדִ֔ים וַעֲבַדְתֶּ֖ם אֹתָֽנוּ׃
Jika ia sanggup berperang melawan aku dan mengalahkan aku, maka kami akan menjadi hamba-hambamu; tetapi jika aku dapat mengalahkan dia dan membunuhnya, maka kamu akan menjadi hamba-hamba kami dan melayani kami.
Rashi
Is this not Dovid, the king of the land. They said to Achish, "There was a stipulation between us: 'If he will be able to fight me and kill me, then we will become your slaves.'10Above 17:9. You have no choice but to get off your throne and let him become king of this land."
