I was hanging out in Deuteronomy 8 the other day, and came across this:
So He humbled you, allowed you to hunger, and fed you with manna which you did not know nor did your fathers know, that He might make you know that man shall not live by bread alone; but man lives by every word that proceeds from the mouth YHVH.
In context, we see that Moses was on the mountain for forty days with no bread, and at the end, he received YHVH's instructions - written on stone tablets.
Moses, a foreshadow of the Messiah, was given the Word - the Bread of Life - on stones.
Fast forward to Yeshua, spending His own forty days in the wilderness with no bread. The accuser, who knows the scriptures probably better than anyone, challenged Yeshua to turn the mountain stones into bread. Yeshua went right back to Deuteronomy 8 and quoted the aforementioned verse.
Several chapters later, we find Yeshua teaching His disciples how to pray. About halfway through, He said "give us this day our daily bread." Do you think He is talking about food? Hmmm, just a few verses later He told His disciples not to worry about what they shall eat or drink. It looks to me like He is talking about feasting on the daily Word!
We see another connection in the very next chapter, when Yeshua said Or what man is there among you who, if his son asks for bread, will give him a stone? Yeshua is saying that it is a good thing to desire the Bread, the One who fulfilled everything that was written on the stones of Sinai.
The purpose of the law, written on stone and given to Moses, was to reveal our sinful nature and demonstrate our need for redemption. Yeshua, the Bread of Life, fulfilled the law, gave His life for us, and became our Chief Cornerstone in Whom we are to place our trust.
John 6 is full of references to bread. The chapter begins with Yeshua feeding the 5000. The next day, people showed up for another free meal, and were taught about the Everlasting Bread instead.
Then Jesus said to them, “Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. For the bread of God is He who comes down from heaven and gives life to the world.
This caused grumbling among some of the people. Yeshua continued, "I am the bread of life. Your fathers ate the manna in the wilderness, and are dead. This is the bread which comes down from heaven, that one may eat of it and not die. I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.”
