Isaiah 22:7

7.And the choice of the valleys (84) was full of chariots. I do not find fault with the translation given by some interpreters, “in a chariot of horsemen,” but I have chosen rather to translate literally the words of the Prophet; for I think that he means “a military chariot.” At that time they made use of two kinds of chariots, one for carrying baggage, and another for the field of battle. Here he means those chariots in which the horsemen rode.

Had it been a threatening, it would have been proper to translate it in the future tense, “And it shall be;” but as the words which immediately follow are in the past tense, and as there is reason to believe that the Prophet is relating events which have already taken place, I have not hesitated to make this beginning agree with what follows. “The choice of the valleys” means “the choicest valleys.” He reminds the Jews of those straits to which they were reduced when the enemies were at their gates. They ought at that time to have sought help from God; but those wretched people became more strongly alienated from God, and more shamefully manifested their rebellion, which shewed them to be men utterly abandoned, and therefore he reproaches them with this hardened obstinacy.
