Psalm 53

The fool says in his heart, “There is no God.”
They are corrupt, doing abominable iniquity;
there is none who does good.
God looks down from heaven
on the children of man
to see if there are any who understand,
who seek after God.
They have all fallen away;
together they have become corrupt;
there is none who does good,
not even one.
Have those who work evil no knowledge,
who eat up my people as they eat bread,
and do not call upon God?
There they are, in great terror,
where there is no terror!
For God scatters the bones of him who encamps against you;
you put them to shame, for God has rejected them.
Oh, that salvation for Israel would come out of Zion!
When God restores the fortunes of his people,
let Jacob rejoice, let Israel be glad.

Numbers 16-18

And Moses said to Korah, “Hear now, you sons of Levi: is it too small a thing for you that the God of Israel has separated you from the congregation of Israel, to bring you near to himself, to do service in the tabernacle of the LORD and to stand before the congregation to minister to them, and that he has brought you near him, and all your brothers the sons of Levi with you? And would you seek the priesthood also? Therefore it is against the LORD that you and all your company have gathered together. What is Aaron that you grumble against him?”

Then Korah assembled all the congregation against them at the entrance of the tent of meeting. And the glory of the LORD appeared to all the congregation.
And the LORD spoke to Moses and to Aaron, saying, “Separate yourselves from among this congregation, that I may consume them in a moment.” And they fell on their faces and said, “O God, the God of the spirits of all flesh, shall one man sin, and will you be angry with all the congregation?” And the LORD spoke to Moses, saying, “Say to the congregation, Get away from the dwelling of Korah, Dathan, and Abiram.”
Then Moses rose and went to Dathan and Abiram, and the elders of Israel followed him. And he spoke to the congregation, saying, “Depart, please, from the tents of these wicked men, and touch nothing of theirs, lest you be swept away with all their sins.” So they got away from the dwelling of Korah, Dathan, and Abiram. And Dathan and Abiram came out and stood at the door of their tents, together with their wives, their sons, and their little ones. And Moses said, “Hereby you shall know that the LORD has sent me to do all these works, and that it has not been of my own accord. If these men die as all men die, or if they are visited by the fate of all mankind, then the LORD has not sent me. But if the LORD creates something new, and the ground opens its mouth and swallows them up with all that belongs to them, and they go down alive into Sheol, then you shall know that these men have despised the LORD.”
And as soon as he had finished speaking all these words, the ground under them split apart. And the earth opened its mouth and swallowed them up, with their households and all the people who belonged to Korah and all their goods. So they and all that belonged to them went down alive into Sheol, and the earth closed over them, and they perished from the midst of the assembly. And all Israel who were around them fled at their cry, for they said, “Lest the earth swallow us up!” And fire came out from the LORD and consumed the 250 men offering the incense.

On the next day Moses went into the tent of the testimony, and behold, the staff of Aaron for the house of Levi had sprouted and put forth buds and produced blossoms, and it bore ripe almonds. Then Moses brought out all the staffs from before the LORD to all the people of Israel. And they looked, and each man took his staff. And the LORD said to Moses, “Put back the staff of Aaron before the testimony, to be kept as a sign for the rebels, that you may make an end of their grumblings against me, lest they die.” Thus did Moses; as the LORD commanded him, so he did.

To the Levites I have given every tithe in Israel for an inheritance, in return for their service that they do, their service in the tent of meeting, so that the people of Israel do not come near the tent of meeting, lest they bear sin and die. But the Levites shall do the service of the tent of meeting, and they shall bear their iniquity. It shall be a perpetual statute throughout your generations, and among the people of Israel they shall have no inheritance. For the tithe of the people of Israel, which they present as a contribution to the LORD, I have given to the Levites for an inheritance. Therefore I have said of them that they shall have no inheritance among the people of Israel.”
