Numbers 16:16-18

¹⁶Moses said to Korah, “You and all your company go before Yahweh, you, and they, and Aaron, tomorrow.

¹⁷Each man take his censer and put incense on it, and each man bring before Yahweh his censer, two hundred fifty censers; you also, and Aaron, each with his censer.”

¹⁸They each took his censer, and put fire in it, and laid incense on it, and stood at the door of the Tent of Meeting with Moses and Aaron.
