Numbers 16:32

Then there were the miracles of the seditious among the people of God. They separated themselves from the divinely ordered community. They were swallowed alive by the earth, as a visible token of an invisible punishment.

In the Old Testament, as, for instance, in the case of Korah and the men who dared to enter the priesthood without being called to it and by the severity of the wrath which came upon them to their utter destruction, we see how grave a thing it is to do that which is unsuitable as regards the person.

And that He might increase in them this fear, immediately, by the mouth of offence, the rod of His chastisement was revealed, and after the offence the Chastiser gave them no respite, because their servitude was not worthy of His longsuffering. Above their head the rod of justice hung continually, and immediately they committed sin they were chastened, and at the time of their offence they were beaten, and at the entrance of the path of their sins they forthwith received rebuke; for longsuffering teacheth the foolish servant contempt, and in order that that stupid nation, which in the manner of an evil-doing servant, sat in the house of God, might not [learn] contempt, the Chastiser took away longsuffering, especially when they went forth from Egypt.

But the people, in their ignorance, when instruction had been delivered unto them, forgot it, and they never kept in remembrance the meditation of the commandments of God, and they were frequently punished with severity, so that, if it were only through fear of chastisement, they might lay hold upon the remembrance of instruction. The man who gathered sticks on the Sabbath day was stoned by all the congregation; and the earth opened and swallowed up others who were called by Moses, and who scorned him and came not; and fire went forth suddenly, and burnt up the bodies of others who thought lightly of his priestly office, and who sought honour for themselves; and others, who in the guise of paying honour, brought strange fire out of season, were burnt up by a tongue of fire which went forth from the tabernacle, and they perished; and others, because they asked for flesh and rejected the bread of angels, were tortured by the indigestion which came upon them; and others who went astray as concerning the calf, were pierced through by the swords of the Levites; and others, who were the cause of the revolt at the waters of trial were set apart for destruction; and others who murmured against the Lord perished by fiendish snakes; and likewise they all, because they strove…
