Numbers 16:18-19

16:18 So everyone took his censer, put fire in it, and set incense on it, and stood at the entrance of the tent of meeting, with Moses and Aaron. 16:19 When ¹  Korah assembled the whole community against them at the entrance of the tent of meeting, then the glory of the Lord appeared to the whole community.

[16:19]  ¹ tn This clause is clearly foundational for the clause that follows, the appearance of the Lord; therefore it should be subordinated to the next as a temporal clause (one preterite followed by another preterite may be so subordinated).
