וְכָל־אַנְשֵׁ֤י בֵיתוֹ֙ יְלִ֣יד בָּ֔יִת וּמִקְנַת־כֶּ֖סֶף מֵאֵ֣ת בֶּן־נֵכָ֑ר נִמֹּ֖לוּ אִתּֽוֹ׃ (פ)
At ang lahat ng mga tao ng kaniyang bahay, ang ipinanganak sa bahay at ang binili ng salapi mula sa dayuhan, ay tinuli na kasama niya.
Chizkuni
וכל אנשי ביתו, “and all the males of his household;” where the previous verse had spoken only of Avraham, this one speaks of all the members of his household. This included slaves purchased by him, not born to members of his household, as well as anyone belonging to Yishmael.
Radak
נמולו אתו, by Avraham. The root of both נמול and נמולו is the verb נמל.
Chizkuni
נמולו אתו, it does not say: מלו אתו, which would have implied that they were circumcised against their will, but they were all willing participants in this procedure.
