The Hidden Manna, White Stone
Revelation 2:17 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give some of the hidden manna. I will also give him a white stone with a new name written on it, known only to him who receives it.
Exudus 16:31-35 The people of Israel called the bread manna. It was white like coriander seed and tasted like wafers made with honey. Moses said, "This is what the LORD has commanded: 'Take an omer of manna and keep it for the generations to come, so they can see the bread I gave you to eat in the desert when I brought you out of Egypt.' " So Moses said to Aaron, "Take a jar and put an omer of manna in it. Then place it before the LORD to be kept for the generations to come." As the LORD commanded Moses, Aaron put the manna in front of the Testimony, that it might be kept. The Israelites ate manna forty years, until they came to a land that was settled; they ate manna until they reached the border of Canaan.
