Before your tender briars develop into hardened thorns lit. before your tender briars know hardened thorns. That before your tender briars know to be hardened thorns, i.e., before the children of the wicked grow up.

with vigor, with wrath i.e., with might, with strength, and with wrath will the Holy One, blessed be He, drive them away as [with] a storm wind.

with vigor חי is an expression of might.
