This four inch scroll is one of the Silver Scrolls, which contain the oldest known Biblical passages. Written about 600 BC, they were discovered in 1979 in Jerusalem at a place outside the Old City known as Ketef Hinnom. The Hebrew language text on the pictured scroll is taken from Numbers 6:24-26 and reads, "May Yahweh bless you and keep you; May Yahweh cause his face to shine upon you and grant you peace."
Shalom: The literal translation is " Peace" Although It can be used also to say hello and goodbye. Which meaning make us think that the actual interpretation is: Come in peace - While greeting a person. And Go in peace.
