Lalu Abraham membawa Ismael, anaknya, dan semua yang lahir di rumahnya dan semua yang dibeli dengan uangnya, yaitu setiap laki-laki di antara orang-orang di rumah Abraham, dan ia menyunat kulit khatan mereka pada hari itu juga, seperti yang telah difirmankan Allah kepadanya.
Da'at Zekenim
אז ישיר משה, “this is when Moses broke out with a song, etc.;” Moses now apologised for when in frustration he had said to G–d, also using the word מאז, “from then,” that since he had assumed his position the fortunes of the Jewish people had worsened (Exodus 5,23). He therefore used the same word when now singing G–d’s praises. An alternate interpretation: the numerical value of the word אז is 8. He hinted that the Jewish people had merited this miraculous salvation on account of the circumcision which is performed on the eighth day of the infant’s life. The verse לגוזר ים סוף לגזרים, “Who splits apart the Sea of reeds into separate sections,” (Psalms 136,13) is used as a Scriptural reference to this. The Hebrew word וימל, “he circumcised,” describing Avraham performing circumcision in Genesis 17,23, is translated by the Targum as וגזר.
Da'at Zekenim
וירא אליו ה' באלוני ממרא, “The Lord appeared to him at eloney mamre, etc.” According to Rashi, Mamre was the man who had advised Avraham strongly to carry out G–d’s command to circumcise himself. This is why this revelation took place while Avraham was on his property. The obvious question here is why someone of the stature of Avraham needed to consult with his friends about if and how to relate to G–d’s commandment. He had been tested as to his faith in Him on ten occasions, and he had passed all these tests without consulting with anyone, why would he suddenly feel the need to “consult” anyone? The answer clearly must be that Avraham did not “consult” with anyone in order to decide if to carry out G–d’s command; he only asked his friends if to perform this commandment on himself in the privacy of his tent or publicly, in order to demonstrate his loyalty to G–d’s command. His purpose in doing so publicly would be in order to encourage others to emulate his example. When the Torah described him as performing the act of circumcision בעצם היום הזה, (Genesis 17,23) these words mean: “in broad daylight, for all to see.” Mamre was given credit by G–d for having given Avraham this advice. A different interpretation of our verse: Avraham consulted with Mamre regarding the exact part of his body where the “circumcision” had to be performed. He therefore advised him to perform this operation on the organ that represented his masculinity. After all, G–d had restricted the performance of this rite to the males of the species. (17,10) He also advised him to commence with circumcising himself and his son Ishmael first. Once his slaves and friends would observe this, most of them would follow willingly without protest. The Torah testifies in chapter 17, verse 27 that all the members of Avraham’s household (including hired help) were circumcised on the same day that he was. If you were to ask why Mamre, himself, who gave Avraham this advice, did not have himself circumcised also, the answer is that eventually he did do so as reported in a Midrash.
Rashi
וירא אליו AND THE LORD APPEARED UNTO HIM to visit the sick man. R. Hama the son of Hanina said: it was the third day after his circumcision and the Holy One, blessed be He, came and enquired after the state of his health (Bava Metzia 86b)
Rashi
באלוני ממרא BY THE TEREBINTHS OF MAMRÉ — It was he (Mamre) who advised him (Abraham) regarding the circumcision and therefore He revealed himself to him in his (Mamre’s) territory (Genesis Rabbah 42:8).
Rashi
literally, יֹשֵׁב WAS SITTING — The word is written ישב (without the ו) and therefore may be translated “he sat”: He wished to rise, but the Holy One, blessed be He, said to him, Sit and I will stand. You shall form an example to your descendants — that I, in time to come, will stand in the assembly of the judges while they will sit, as it is said, (Psalms 82:1) “God standeth in the assembly of the judges” (Genesis Rabbah 48:7)
Rashi
פתח האהל AT THE TENT-DOOR — that he might see whether anyone passed by, and invite him into the house
Rashi
כחום היום IN THE HEAT OF THE DAY — The Holy One, blessed be He, brought the sun out of its sheath that he might not be troubled by travellers, and when He perceived that he was grieved that no travellers came He brought to him angels in the form of men (Bava Metzia 86b).
