Not eaten bread, i.e. common bread purchased by your own money, or made by your own hands, but heavenly and angelical bread, Deuteronomy 8:3 Psalms 78:24,25. You have subsisted without bread, the staff of life. Neither wine or strong drink, but only water out of the rock. The Lord your God; the Lord omnipotent and all-sufficient for your provision, without the help of any creatures, and your God in covenant with you, who hath a true affection to you, and fatherly care of you, even when ordinary means fail.
