Numbers 16:17-19

Young's Literal Translation

¹⁷ and take ye each his censer, and ye have put on them perfume, and brought near before Jehovah, each his censer, two hundred and fifty censers; and thou and Aaron, each his censer.'

¹⁸ And they take each his censer, and put on them fire, and lay on them perfume, and they stand at the opening of the tent of meeting, with Moses and Aaron.

¹⁹ And Korah assembleth against them all the company unto the opening of the tent of meeting, and the honour of Jehovah is seen by all the company.
