Комментарий к Шмот 32:26

מי לה' אלי means, WHOEVER IS FOR THE LORD let him come TO ME.

AND MOSES STOOD IN THE GATE OF THE CAMP. This is connected with what is said in the preceding verse, thus stating that when Moses saw that the people would be a source of derision and disgrace amongst their enemies, and would thereby profane the Name of G-d, he stood in the gate of the camp and called out loudly, Whoso is on the Eternal’s side, let him come unto me; and they killed publicly all those who worshipped the calf, so that the matter be heard about amongst their enemies, and G-d’s Name would thus be sanctified, in place of the profanation that they had caused.

Whoever is for Ad-noy [come] to me. Moshe could not have been referring to everyone who did not worship the calf, for that would have included the majority of the people. Rather, he was calling upon those whose intentions were pure and who would give all they owned for God’s honor.
