'Brier' in the Bible

Instead of the thorn shall come up the fir tree; and instead of the brier shall come up the myrtle tree: and it shall be to Yahweh for a name, for an everlasting sign that shall not be cut off."

There shall be no more a pricking brier to the house of Israel, nor a hurting thorn of any that are around them, that did despite to them; and they shall know that I am the Lord Yahweh.

The best of them is like a brier. The most upright is worse than a thorn hedge. The day of your watchmen, even your visitation, has come; now is the time of their confusion.
