When the manuscript was ready, its authors had to determine the right time at which to read it; they found their desired opportunity in the fast proclaimed in the ninth month. This was evidently an extraordinary fast, appointed in view of some pressing danger; and, in the year following the battle of Carchemish, this would naturally be the advance of Nebuchadnezzar. As our incident took place in the depth of winter, the months must be reckoned according to the Babylonian year, which began in April; and the ninth month, Kisleu, would roughly correspond to our December. The dreaded invasion would be looked for early in the following spring, "at the time when kings go out to battle."[32] Jeremiah does not seem to have absolutely determined from the first that the reading of the roll by Baruch was to be a substitute for his own presence. He had probably hoped that some change for the better in the situation might justify his appearance before a great gathering in the Temple. But when the time came he was "hindered"[33]--we are not told how--and could not go into the Temple. He may have been restrained by his own prudence, or dissuaded by his friends, like Paul when he would have faced the mob in the theatre at Ephesus; the hindrance may have been some ban under which he had been placed by the priesthood, or it may have been some unexpected illness, or legal uncleanness, or some other passing accident, such as Providence often uses to protect its soldiers till their warfare is accomplished.
