Numbers 17:4-7

⁴And Eleazar the son of Aaron the priest took the brazen censers, which the men who had been burnt brought near, and they put them as a covering on the altar:

⁵a memorial to the children of Israel that no stranger might draw nigh, who is not of the seed of Aaron, to offer incense before the Lord; so he shall not be as Core and as they that conspired with him, as the Lord spoke to him by the hand of Moses.

⁶And the children of Israel murmured the next day against Moses and Aaron, saying, Ye have killed the people of the Lord.

⁷And it came to pass when the congregation combined against Moses and Aaron, that they ran impetuously to the tabernacle of witness; and the cloud covered it, and the glory of the Lord appeared.
