'Briers' in the Bible

"Now as for you, Son of Man, never be afraid of them or of anything they have to say, because being with them will be like settling down to live among briers, thorn bushes, and scorpions! Don't be afraid of anything they have to say, and don't be awed by their appearance, since they are a rebellious group.

"The house of Israel will never again suffer from painful briers and sharp thorn bushes that surround them on every side, and they will learn that I am the LORD.
