쉐모트 (출애굽기) 5:20

ויפגעו AND THEY MET — men of Israel met — את משה ואהרן וגו׳ MOSES AND AARON etc.; Our Rabbis explained that wherever it speaks of people “quarelling” (2:13; cf. Rashi on that verse) or “standing” these were Dathan and Abiram about whom it is stated (Numbers 16:27) “[And Dathan and Abiram] came out standing” (Nedarim 64b).

וַֽיִּפְגְּעוּ֙ אֶת־מֹשֶׁ֣ה וְאֶֽת־אַהֲרֹ֔ן נִצָּבִ֖ים לִקְרָאתָ֑ם בְּצֵאתָ֖ם מֵאֵ֥ת פַּרְעֹֽה׃

And they met Moshe and Aharon, who stood in the way, as they came out from Par῾o.
