Definition and Context:
In biblical terms, "raw flesh" refers to meat that has not been cooked or prepared according to the dietary laws prescribed in the Scriptures. The consumption of raw flesh is addressed in various passages, often in the context of ritual purity and dietary regulations given to the Israelites.

Biblical References:

1. Leviticus 7:26-27 :
"You must not eat the blood of any bird or animal in any of your dwellings. Whoever eats any blood will be cut off from his people."
While this passage specifically mentions blood, it underscores the broader principle of consuming meat in a manner that respects God's commandments, which includes proper preparation and cooking.

2. Leviticus 17:10-14 :
"If anyone from the house of Israel or a foreigner living among them eats any blood, I will set My face against that person and cut him off from his people. For the life of the flesh is in the blood, and I have given it to you to make atonement for your souls on the altar; for it is the blood that makes atonement for the soul."
This passage highlights the sacredness of blood, which is not to be consumed. The prohibition against eating raw flesh is closely tied to the prohibition against consuming blood, as raw meat would still contain blood.

3. Genesis 9:4 :
"But you must not eat meat with its lifeblood still in it."
This command was given to Noah and his descendants after the flood, establishing a universal principle that predates the Mosaic Law. It emphasizes the importance of draining blood from meat before consumption.

4. Ezekiel 24:10-11 :
"Heap on the wood, kindle the fire, boil the meat well, and mix in the spices. Let the bones be burned. Set the empty pot on the coals, so that it becomes hot and its copper glows, so that its impurities may be melted and its dross consumed."
This metaphorical passage uses the imagery of cooking meat to convey a message of purification and judgment. It reflects the cultural understanding of cooking as a means of preparing food properly.

Theological Significance:
The prohibition against eating raw flesh is deeply rooted in the theological understanding of life and holiness. Blood, representing life, is sacred and reserved for atonement purposes. The consumption of raw flesh, therefore, is not merely a dietary concern but a spiritual one, reflecting obedience to God's commands and respect for the sanctity of life.

Cultural and Historical Context:
In ancient Near Eastern cultures, dietary practices were often linked to religious beliefs and rituals. The Israelites were set apart by God with specific laws that distinguished them from surrounding nations. These laws, including those concerning the consumption of meat, served to maintain their identity as God's chosen people and to promote physical and spiritual purity.

Practical Implications:
For the Israelites, adherence to dietary laws, including the prohibition of raw flesh, was a tangible expression of their covenant relationship with God. It served as a daily reminder of their distinctiveness and their call to holiness. In contemporary Christian practice, while the specific dietary laws of the Old Testament are not binding, the principles of honoring God with one's body and respecting the sanctity of life remain relevant.
