Isaiah 8:9

Associate yourselves Rather: Be exasperated. A.V. follows the Targum and Vulgate, whose translation is based on a wrong grammatical analysis of the word (the root being râ-a-, not râ-âh).

and ye shall be broken in pieces Lit.: and be dismayed, a consecutive imperative (Davidson, Synt.§ 64), forming the apodosis of a conditional sentence.

gird yourselves for battle against the cause of Jehovah.
