Deuteronomy 8:3 (a) This bread is a type of CHRIST, the living Bread. GOD gave it to Israel in a miraculous way. He is the living bread which sustains the lives of GOD's people. It was always pure white. It was sweet. There was enough for all. (See also John 6:49; Hebrews 9:4).
Revelation 2:17 (a) This bread is a type of some sort of unseen and unknown blessings which are given by GOD for the blessing of His people when they live victorious lives for Him. It is a gift that is lovely, precious, attractive and satisfying, but the character of it is unknown.
