And Aaron, lifting up his hands to the people, gave them a blessing; and he came down from offering the sin-offering, and the burned offering, and the peace-offerings.
The sons of Amram: Aaron and Moses; and Aaron was made separate and holy, he and his sons for ever, for the care of the most holy things and the burning of offerings before the Lord, to do his work and give blessings in his name for ever.
At that time the Lord had the tribe of Levi marked out to take up the ark of the Lord's agreement, to be before the Lord and to do his work and to give blessings in his name, to this day.
Then the priests, the sons of Levi, are to come near; for they have been marked out by the Lord your God to be his servants and to give blessings in the name of the Lord; and by their decision every argument and every blow is to be judged:
Not giving back evil for evil, or curse for curse, but in place of cursing, blessing; because this is the purpose of God for you that you may have a heritage of blessing.
