אִם־יוּכַ֞ל לְהִלָּחֵ֤ם אִתִּי֙ וְהִכָּ֔נִי וְהָיִ֥ינוּ לָכֶ֖ם לַעֲבָדִ֑ים וְאִם־אֲנִ֤י אֽוּכַל־לוֹ֙ וְהִכִּיתִ֔יו וִהְיִ֤יתֶם לָ֙נוּ֙ לַעֲבָדִ֔ים וַעֲבַדְתֶּ֖ם אֹתָֽנוּ׃
그가 능히 싸워서 나를 죽이면 우리가 너희의 종이 되겠고 만일 내가 이기어 그를 죽이면 너희가 우리의 종이 되어 우리를 섬길 것이니라
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."
