'Edge' in the Bible

Why do you make use of this saying about the land of Israel, The fathers have been tasting bitter grapes and the children's teeth are on edge?

Be pointed to the right, to the left, wherever your edge is ordered.

See, then, I am against you and against your streams, and I will make the land of Egypt an unpeopled waste, from Migdol to Syene, even as far as the edge of Ethiopia.

And these are the measures of the altar in cubits: (the cubit being a cubit and a hand's measure;) its hollow base is a cubit high and a cubit wide, and it has an overhanging edge as wide as a hand-stretch all round it:

And the shelf is fourteen cubits long and fourteen cubits wide, on its four sides; the edge round it is half a cubit; the base of it is a cubit all round, and its steps are facing the east.

You are to take some of its blood and put it on the four horns and on the four angles of the shelf and on the edge all round: and you are to make it clean and free from sin.

And he said to me, Son of man, have you seen this? Then he took me to the river's edge.

And he took me back, and I saw at the edge of the river a very great number of trees on this side and on that.

And by the edge of the river, on this side and on that, will come up every tree used for food, whose leaves will ever be green and its fruit will not come to an end: it will have new fruit every month, because its waters come out from the holy place: the fruit will be for food and the leaf will make well those who are ill.
