In the morning the Lord will show who belongs to him and who is holy, and he will have that person come near him

 Numbers 15-17

Speak to the Israelites and say to them: ‘After you enter the land I am giving you as a home and you present to the Lord food offerings from the herd or the flock, as an aroma pleasing to the Lord—whether burnt offerings or sacrifices, for special vows or freewill offerings or festival offerings— then the person who brings an offering shall present to the Lord a grain offering of a tenth of an ephah of the finest flour mixed with a quarter of a hin of olive oil. With each lamb for the burnt offering or the sacrifice, prepare a quarter of a hin of wine as a drink offering.

With a ram prepare a grain offering of two-tenths of an ephah of the finest flour mixed with a third of a hin of olive oil, and a third of a hin of wine as a drink offering. Offer it as an aroma pleasing to the Lord.

When you prepare a young bull as a burnt offering or sacrifice, for a special vow or a fellowship offering to the Lord, bring with the bull a grain offering of three-tenths of an ephah of the finest flour mixed with half a hin of olive oil.

You and the foreigner shall be the same before the Lord: The same laws and regulations will apply both to you and to the foreigner residing among you.’

When Moses heard this, he fell facedown. Then he said to Korah and all his followers: “In the morning the Lord will show who belongs to him and who is holy, and he will have that person come near him. 

He has brought you and all your fellow Levites near himself, but now you are trying to get the priesthood too. It is against the Lord that you and all your followers have banded together. Who is Aaron that you should grumble against him?”

The Lord said to Moses and Aaron, “Separate yourselves from this assembly so I can put an end to them at once.

Moses got up and went to Dathan and Abiram, and the elders of Israel followed him. He warned the assembly, “Move back from the tents of these wicked men! Do not touch anything belonging to them, or you will be swept away because of all their sins.”

As soon as he finished saying all this, the ground under them split apart and the earth opened its mouth and swallowed them and their households, and all those associated with Korah, together with their possessions. They went down alive into the realm of the dead, with everything they owned; the earth closed over them, and they perished and were gone from the community. At their cries, all the Israelites around them fled, shouting, “The earth is going to swallow us too!”

So Eleazar the priest collected the bronze censers brought by those who had been burned to death, and he had them hammered out to overlay the altar, 40 as the Lord directed him through Moses. This was to remind the Israelites that no one except a descendant of Aaron should come to burn incense before the Lord, or he would become like Korah and his followers.

But 14,700 people died from the plague, in addition to those who had died because of Korah. Then Aaron returned to Moses at the entrance to the tent of meeting, for the plague had stopped.

Why?

The Lord is Holy; who can despise the servants of the Lord? No one, every God's people is chosen by the Lord. If anyone did something wrong, the Lord will judge them. We do not have the authority to judge other brothers or sisters.

God is love and faithful. So we should honor the Holy name of the Lord, and love each other, with love and grace, and keep ourselves from sins.

How?

Do my best to be a good Christ-like Christian, with love, faith, and hope.
