'Pricks' in the Bible

But if you do not drive out the inhabitants of the land from before you, then those you let remain of them will be like pricks in your eyes and like thorns in your sides, and they will attack you in the land in which you live.

The way of the lazy is like a hedge of thorns [it pricks, lacerates, and entangles him],But the way [of life] of the upright is smooth and open like a highway.
