Your clothing grew not old upon you, neither did your foot swell, these forty years.

Worn, for want of shoes, chap. xxix. 5. (Chaldean) This miracle of the Hebrews, being so well provided with raiment in a desert country, is mentioned, 2 Esdras ix. 21. Cosmas (B. v.) allows only that merchants constantly supplied them, and Abenezra thinks that they had brought plenty for change out of Egypt. (Calmet)
But the Scripture seems to acknowledge something more wonderful; namely, the good condition of the people's feet, and of their garments, after they had been worn for such a length of time. As their numbers had not increased, the children might be supplied with the clothes of the deceased; so that there is no need of making the miracle still greater, by asserting, as some have done, that the garments grew larger with the bodies of those who wore them. (Haydock)
The miracle was in favour both of good and bad, like manna (Tirinus)
