Now Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it and laid incense on it and offered unauthorized fire before the LORD, which he had not commanded them. And fire came out from before the LORD and consumed them, and they died before the LORD. Then Moses said to Aaron, “This is what the LORD has said: ‘Among those who are near me I will be sanctified, and before all the people I will be glorified.’” And Aaron held his peace.
2 Samuel 6:5-11
And David and all the house of Israel were celebrating before the LORD, with songs and lyres and harps and tambourines and castanets and cymbals. And when they came to the threshing floor of Nacon, Uzzah put out his hand to the ark of God and took hold of it, for the oxen stumbled. And the anger of the LORD was kindled against Uzzah, and God struck him down there because of his error, and he died there beside the ark of God. And David was angry because the LORD had broken out against Uzzah. And that place is called Perez-uzzah to this day. And David was afraid of the LORD that day, and he said, “How can the ark of the LORD come to me?” So David was not willing to take the ark of the LORD into the city of David. But David took it aside to the house of Obed-edom the Gittite. And the ark of the LORD remained in the house of Obed-edom the Gittite three months, and the LORD blessed Obed-edom and all his household.
Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin. Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need.
