Deuteronomy 29:5,6

What less than a standing miracle was this, that Israel was fed, clothed, and strengthened, through forty years, when their garments waxed not old, and the very sandals, with which they came out of Egypt, did not wear out amidst the rugged road of the wilderness. And what is it now, but the continuation of the same miraculous power, which is displayed in sustaining the spiritual Israel through all their wilderness state, by which their souls are fed with the bread of life, and the garments of salvation by JESUS remain unsullied, through a world of sin and corruption both within and without them.
