The Ketef Hinnom scrolls, dating to around 2,600 years ago. Discovered while excavating in the City of David in 1979 they have the Priestly Blessing written on them from Numbers.
The Lord said to Moses, “Tell Aaron and his sons, ‘This is how you are to bless the Israelites. Say to them:
“‘“The Lord bless you and keep you; the Lord make his face shine on you and be gracious to you; the Lord turn his face toward you and give you peace.”’
“So they will put my name on the Israelites, and I will bless them.”
