Now it was during the course of the events just sketched, but before their culmination in the fall of Babylon, that chs. xliii.-xlviii. were composed. That, at least, is what they themselves suggest. In three passages, which deal with Cyrus or with Babylon, some of the verbs are in the past, some in the future. Those in the past tense describe the calling and full career of Cyrus or the beginning of preparations against Babylon. Those in the future tense promise Babylon's fall or Cyrus' completion of the liberation of the Jews. Thus, in ch. xliii. 14 it is written: _For your sakes I have sent to Babylon, and I will bring down as fugitives all of them, and the Chaldeans in the ships of their rejoicing_. Surely these words announce that Babylon's fate was already on the way to her, but not yet arrived. Again, in the verses which deal with Cyrus himself, xlv. 1-6, which we have partly quoted, the Persian is already _grasped by his right hand by God, and called_; but his career is not over, for God promises to do various things for him. The third passage is ver. 13 of the same chapter, where Jehovah says, _I have stirred him up in righteousness, and_, changing to the future tense, _all his ways will I level; he shall build My city, and My captivity shall he send away_. What could be more precise than the tenor of all these passages? If people would only take our prophet at his word; if with all their belief in the inspiration of the text of Scripture, they would only pay attention to its grammar, which surely, on their own theory, is also thoroughly sacred, then there would be to-day no question about the date of Isa. xl.-xlviii. As plainly as grammar can enable it to do, this prophecy speaks of Cyrus' campaign against Babylon as already begun, but of its completion as still future. Ch. xlviii., it is true, assumes events as still farther developed, but we will come to it afterwards. During Cyrus' preparations, then, for invading Babylonia, and in prospect of her certain fall, chs. xliii.-xlviii. repeat with greater detail and impetuosity the truths, which we have already gathered from chs. xl.-xlii.
