'Briers' in the Bible

“But you, son of man, do not be afraid of them or their words, though briers and thorns are beside you and you live among scorpions. Don’t be afraid of their words or be discouraged by the look on their faces, for they are a rebellious house.

“The house of Israel will no longer be hurt by prickly briers or painful thorns from all their neighbors who treat them with contempt. Then they will know that I am the Lord Yahweh.
