Numbers 16:31 And it came to pass, as he had made an end of speaking all these words, that the ground clave asunder that was under them. 32 And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods.
Numbers 16:33 They, and all that appertained to them, went down alive into the pit, and the earth closed upon them: and they perished from among the congregation. 34 And all Israel that were round about them fled at the cry of them: for they said, Lest the earth swallow us up also. 35 And there came out a fire from the Lord, and consumed the two hundred and fifty men that offered incense.
These multiple evidences coming from God should have been sufficient to now permanently settle the matter beyond the shadow of a doubt, but the mind that has been damaged by the deliberate imbibing of falsehood, can and will reach a point of no return, where there is nothing else God can do, but to close off probation for such persons.
Numbers 16:41 But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, You have killed the people of the Lord. 42 And it came to pass, when the congregation was gathered against Moses and against Aaron that they looked toward the tabernacle of the congregation: and, behold, the cloud covered it, and the glory of the Lord appeared.
Numbers 16:46 And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the Lord; the plague is begun. 47 And Aaron took as Moses commanded, and ran into the midst of the congregation; and, behold, the plague was begun among the people: and he put on incense, and made an atonement for the people. 48 And he stood between the dead and the living; and the plague was stayed.
May The Lord add His blessing to the study of His word. God bless!
