This is for your health; that they might be stronger to endure that pain and perform that labour which was necessary towards their escape; for God would have them to use all means for their deliverance. For there shall not an hair fall from the head of any of you; a proverbial speech used by the Jews, as 1 Kings 1:52, signifying that they should not suffer the least detriment in their bodies, much less the loss of their lives. Thus God numbereth our hairs, and his providence extendeth over every one of them, as Matthew 10:30 Luke 21:18.
