Numbers 16:15-18

¹⁵And Mosheh was greatly angered, and said before the Lord, Receive not Thou their offering: I have not taken one ass from them, neither have I injured one of them.

¹⁶And Mosheh said to Korach, Be thou and all thy company prepared before the Lord, thou and they and Aharon tomorrow.

¹⁷And take every man his censer, and put sweet incense upon them, each man to offer before the Lord (with) his censer.

¹⁸And they took every man his censer, and set fire in it, and put sweet incense thereon, and stood at the door of the tabernacle of ordinance, with Mosheh and Aharon.
