Numbers 25:6

והנה איש וגו׳ AND BEHOLD, ONE [OF THE CHILDREN OF ISRAEL CAME] The tribe of Simeon gathered to Zimri who was their prince, saying to him. “We are sentenced to death and you remain quiet!?”, — as it is related in the chapter beginning אלו הן הנשרפין (Sanhedrin 82a). את המדינית THE MIDIANITISH WOMAN — Kozbi the daughter of Zur. לעיני משה BEFORE THE EYES OF MOSES — They said to him: “Moses, is this Midianite woman forbidden or permissible as a wife. If you say she is forbidden, then who made Jethro’s daughter, a Midianite woman, permissible to you, etc.” as is related there (Sanhedrin 82a). והמה בכים AND THEY WERE WEEPING — the law (decision on this matter) escaped him and therefore they all burst out into weeping (Sanhedrin 82a). — In the case of the golden calf Moses successfully resisted six hundred thousand men, as it is said, (Exodus 32:20) “And he ground it to powder [and he made the children of Israel drink of it]”, and here his hands were weak (he did not know what to do)?! But this was intentionally caused by God in order that Phineas might come and receive that which was meant for him (Midrash Tanchuma, Balak 20).

וְהִנֵּ֡ה אִישׁ֩ מִבְּנֵ֨י יִשְׂרָאֵ֜ל בָּ֗א וַיַּקְרֵ֤ב אֶל־אֶחָיו֙ אֶת־הַמִּדְיָנִ֔ית לְעֵינֵ֣י מֹשֶׁ֔ה וּלְעֵינֵ֖י כׇּל־עֲדַ֣ת בְּנֵי־יִשְׂרָאֵ֑ל וְהֵ֣מָּה בֹכִ֔ים פֶּ֖תַח אֹ֥הֶל מוֹעֵֽד׃

And, behold, one of the children of Yisra᾽el came and brought to his brethren a Midyanite woman in the sight of Moshe, and in the sight of all the congregation of the children of Yisra᾽el, who were weeping before the door of the Tent of Meeting.
