Numbers 16:21

16:21 “Separate yourselves ¹  from among this community, ²  that I may consume them in an instant.”

Numbers 16:45

16:45 “Get away from this community, so that I can consume them in an instant!” But they threw themselves down with their faces to the ground. ³ 

[16:21]  ¹ tn The verb is הִבָּדְלוּ (hibbadÿlu), the Niphal imperative of בָּדַל (badal). This is the same word that was just used when Moses reminded the Levites that they had been separated from the community to serve the Lord.

[16:21]  ² sn The group of people siding with Korah is meant, and not the entire community of the people of Israel. They are an assembly of rebels, their “community” consisting in their common plot.

[16:45]  ³ tn Heb “they fell on their faces.”
