John Gill's Bible Commentary Ver. 6. Ye have not eaten bread , etc.] 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.
Matthew Henry Commentary
Verses 1-9 - Both former mercies, and fresh mercies, should be thought on by us a motives to obedience. The hearing ear, and seeing eye, and the understanding heart, are the gift of God. All that have them, have the from him. God gives not only food and raiment, but wealth and larg possessions, to many to whom he does not give grace. Many enjoy the gifts, who have not hearts to perceive the Giver, nor the true desig and use of the gifts. We are bound, in gratitude and interest, as wel as in duty and faithfulness, to keep the words of the covenant.
