'Edge' in the Bible

“When you reap the harvest of your land, you are not to reap to the very edge of your field or gather the gleanings of your harvest.

You are not to cut off the hair at the sides of your head or mar the edge of your beard.

“Priests may not make bald spots on their heads, shave the edge of their beards, or make gashes on their bodies.

When you reap the harvest of your land, you are not to reap all the way to the edge of your field or gather the gleanings of your harvest. Leave them for the poor and the foreign resident; I am Yahweh your God.”
