Sinabi niya sa kanila: “Ganito ang sabi ng Walang-Hanggan, ang Diyos ng Israel: ‹Ilagay ng bawat isa sa inyo ang kanyang tabak sa kanyang tagiliran, at magparoo't parito kayo mula sa isang tarangkahan hanggang sa kabilang tarangkahan sa kampo, at patayin ng bawat isa ang kanyang kapatid, ang bawat isa ang kanyang kasama, at ang bawat isa ang kanyang kamag-anak.›”
Rashi
כה אמר הי וגו׳ THUS SAITH THE LORD etc. — Where did he say so? In the command, (Exodus 22:19) “He that sacrificeth unto any god shall utterly be destroyed”. Thus is it stated in the Mechilta.
Ramban
THUS SAITH THE ETERNAL, THE G-D OF ISRAEL. The reason for this expression383‘Elokei’ (the G-d of) Israel — the Divine Name which denotes the attribute of justice. is that since the worshippers of the calf had intended to sacrifice to the G-d of Israel, therefore the attribute of justice extracted punishment from them, because they “mutilated the shoots” [of faith],384See Note 308 above. and besides, for the judgment is G-d’s.385Deuteronomy 1:17. It is for this reason that he [Moses], said of the Levites, for the G-d of Israel hath separated you from the congregation of Israel,386Numbers 16:9. for the Service is to the G-d of Israel, and to His Name they were separated by virtue of this meritorious deed.
Rashbam
איש את אחיו, if he found him worshipping the golden calf.
