And Aaron lifted up his hand toward the people, and blessed them, and came down from offering of the sin offering, and the burnt offering, and peace offerings.
The sons of Amram; Aaron and Moses: and Aaron was separated, that he should sanctify the most holy things, he and his sons forever, to burn incense before the LORD, to minister unto him, and to give the blessing in his name forever.
At that time the LORD set apart the tribe of Levi, to bear the ark of the covenant of the LORD, to stand before the LORD to minister unto him, and to bless in his name, unto this day.
And the priests the sons of Levi shall come near; for them the LORD your God has chosen to minister unto him, and to bless in the name of the LORD; and by their word shall every controversy and every assault be tried:
Not rendering evil for evil, or railing for railing: but on the contrary blessing; knowing that you are unto this called, that you should inherit a blessing.
