'Edges' in the Bible

You shall not round off the side-growth of your heads nor harm the edges of your beard.

They shall not make any baldness on their heads, nor shave off the edges of their beards, nor make any cuts in their flesh.

Ehud made himself a sword which had two edges, a cubit in length, and he bound it on his right thigh under his cloak.

“Behold, I have made you a new, sharp threshing sledge with double edges;You will thresh the mountains and pulverize them,And will make the hills like chaff.

Take also a few in number from them and bind them in the edges of your robes.
