'Sides' in the Bible

And the limit of the east part is the Jordan. This is the heritage of the children of Benjamin, marked out for their families by these limits on all sides.

Then you may be certain that the Lord your God will not go on driving these nations out from before you; but they will become a danger and a cause of sin to you, a whip for your sides and thorns in your eyes, till you are cut off from this good land which the Lord your God has given you.
