'Sides' in the Bible

But the descendants of Levi are to encamp on all sides of the Tent of Meeting so that divine wrath won't fall on the congregation of Israel. The descendants of Levi are to take care of the Tent of Meeting."

but the angel of the LORD stood on a narrow path that crossed the vineyards. It had walls on both sides of the path.

But if you fail to drive out the inhabitants of the land before you, their survivors will become irritants in your eyes and thorns in your sides, to prick your sides and afflict you in the very land in which you'll be living.
