“And when the children of Israel saw it, they said one to another, It is manna (What is it?) for they wist not what it was. And Moses said unto them, This is the bread which the LORD hath given you to eat.” Exodus 16:15

Most other Bible versions ask, “What is it?” where the KJV says, “It is manna.” The word manna means whatness. After they ate the manna, they knew it was bread for them. They no longer had to ask, “What is it?” Though most people know Jesus by name, it isn’t until they are ready to eat of His body that they will no longer have to ask, “Who is He?”
