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 for ever, to burn incense before the LORD, to minister to him, and to bless in his name for ever.
At that time the LORD separated the tribe of Levi, to bear the ark of the covenant of the LORD, to stand before the LORD to minister to him, and to bless in his name, to this day.
And the priests the sons of Levi shall come near; for them the LORD your God has chosen to minister to him, and to bless in the name of the LORD; and by their word shall every controversy and every stroke be tried:
Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that you are thereunto called, that you should inherit a blessing.
