Shewbread

Lev 24:5 And thou shalt take fine flour, and bake twelve cakes thereof: two tenth deals shall be in one cake.
Lev 24:6 And thou shalt set them in two rows, six on a row, upon the pure table before the LORD.
Lev 24:7 And thou shalt put pure frankincense upon each row, that it may be on the bread for a memorial, even an offering made by fire unto the LORD.
Lev 24:8 Every sabbath he shall set it in order before the LORD continually, being taken from the children of Israel by an everlasting covenant.
Lev 24:9 And it shall be Aaron's and his sons'; and they shall eat it in the holy place: for it is most holy unto him of the offerings of the LORD made by fire by a perpetual statute.

How large were these shew bread loaves? Each loaf contained from three to four quarts of unleavened flour. One quart is four cups of flour. When I make a one pound loaf of bread, I use two cups of flour. So these loaves were from twelve to sixteen cups of flour for each one. Each loaf weighed from six to eight pounds. There were twelve of these loaves in two rows of six, representing the twelve tribes of Israel. They were placed before the LORD in the holy place of the tabernacle on a gold covered table. Pure frankincense was put on each row probably in plates and burned as a memorial offering to the LORD. This was to be a continual offering for an everlasting covenant. Aaron and his sons were given the bread each week when it was replaced. David ate the bread in a time of need. It is a representation of an everlasting holiness before the LORD. Jesus is the bread of life, our everlasting covenant before the LORD. He is our spiritual provision as our natural or daily bread is required for our bodies.

Mat 12:1 At that time Jesus went on the sabbath day through the corn; and his disciples were an hungred, and began to pluck the ears of corn, and to eat.
Mat 12:2 But when the Pharisees saw it, they said unto him, Behold, thy disciples do that which is not lawful to do upon the sabbath day.
Mat 12:3 But he said unto them, Have ye not read what David did, when he was an hungred, and they that were with him;
Mat 12:4 How he entered into the house of God, and did eat the shewbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests?

Joh 6:33 For the bread of God is he which cometh down from heaven, and giveth life unto the world.
Joh 6:34 Then said they unto him, Lord, evermore give us this bread.
Joh 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
