Numbers 16:15-19
16:15 Moses was very angry, and he said to the Lord, “Have no respect for their offering! I have not taken so much as one donkey from them, nor have I harmed any one of them!”
16:16 Then Moses said to Korah, “You and all your company present yourselves before the Lord – you and they, and Aaron – tomorrow.
16:17 And each of you take his censer, put incense in it, and then each of you present his censer before the Lord: 250 censers, along with you, and Aaron – each of you with his censer.”
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 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.
