Numbers 11:33-34 KJV
And while the flesh was yet between their teeth, ere it was chewed, the wrath of the Lord was kindled against the people, and the Lord smote the people with a very great plague.  And he called the name of that place Kibroth-hattaavah: because there they buried the people that lusted.
In the wilderness, God supplied Israel daily with Manna. Manna literally means “What is it?”. They didn’t understand what it was because it had no name. It was however God’s choice for Israel at the time. They were supposed to receive it with thankfulness. Unfortunately, it takes understanding to be thankful but the wandering ex - slaves had no understanding. They grumbled about God’s provision and desired something more tangible with flesh and blood. Their craving was supplied but it triggered death in the camp resulting in mass burials.
When Jesus came to earth many years later, He announced that what Israel ate was not bread. They’d eaten Manna (Nameless Food) & died. (John 6:49). They died because they desired more than God was willing to give at the time. Not recognizing God’s supply caused them to desire flesh. Desire for flesh is called Lust. It is usually characterized by meaninglessness. The absence of meaning to life usually genders death. Manna had no name, it therefore led to a desire for flesh that in turn produced death.
Jesus not only gives meaning to life. He gives Life because He is The Bread of Life that has a Name. Identity creates satisfaction. Manna could not satisfy because it had no name. They longed for flesh. Jesus came and said that He is the Living Bread from Heaven. This Bread called Jesus has everything a person desires including Flesh!!!
John 6:49,51 KJV
“Your fathers did eat manna in the wilderness, and are dead.  I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: AND THE BREAD THAT I WILL GIVE IS MY FLESH, which I will give for the life of the world”.
At a spiritually immature level, Christ will represent flesh to some people (As in carnal desire for material things). Yet they will not die because of their desires in that Jesus is God’s real solution. At maturity, they’ll begin to see Jesus as Real Food that gives Life, Nourishment and Everything one needs.
“Eating” in this context refers to Believing. In the Old Testament, they ate physically for temporal satisfaction. In the New Testament, we believe spiritually for Eternal Salvation.
What they ate had no name thus triggering a desire for something else. What we “eat” ( Believe) is called Jesus - He is more than enough!
Their lust led to death and mass burials then. Our desire leads to Life and great resurrection today. Jesus is 100 % satisfaction. There’s no death in Him even if you eat the flesh part of Him. In Christ, the Father patiently waits for you to grow up and be weaned off flesh and established in the true Bread part of Him.
They died for their desire, but we boldly say “Death is swallowed up In Victory”.
In Christ the Bread of Life, there’s no death. Only Life. I desire nothing else outside of Him. Indeed, ALL that I need for Life and Godliness are complete In Jesus who is my Life Eternally. Amen.
