Deuteronomy 29:6
Ye have not eaten bread, neither have ye drunk wine or strong drink: that ye might know that I am the LORD your God.
Ye have not eaten bread,.... Bread made of corn, common bread, of their own preparing, made by the labour of their own hands; but manna, the food of angelS, the bread of heaven:
neither have you drank wine, nor strong drink; only water out of the rock, at least chiefly, and for constancy; though it may be, when they were on the borders of other countries, as of the Edomites, they might obtain some wine for their money:
that ye might know that I am the LORD your God; who was both able and willing to provide food, drink, and raiment for them, and supply them with all good things, and support them without the use of the common necessaries of life; which were abundant proofs of his power and goodness.
