The earliest graves may have been covered by a mound of stones. Though we erect tombstones today, a stone or pebble placed on a head or footstone reminds us of those first humble gravesites. This simple act has come to be a great sign of respect of our deceased loved ones.
It is come to signify that the grave has recently been visited and that the deceased have not been forgotten. To make this simple ritual even more meaningful, some bring a pebble or stone from their own garden to place on the tombstone, or select a brightly colored stone to place at the grave. Placing a stone on the grave of a loved one is a tradition that may be personalized to create meaning and bring comfort.
The Eternal One spoke to Moses and Aaron, saying: "This is the ritual law that the Eternal has commanded: Instruct the Israelite people to bring you a red cow without blemish, in which there is no defect and on which no yoke has been laid." - Numbers 19:1-2
Balak son of Zippor saw all that Israel had done to the Amorites. - Numbers 22:2
