"And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar. And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for mans sake; for the imagination of mans heart is evil from his youth; neither will I again smite any more every thing living, as I have done."
Genesis 8:20-21, KJV
"And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, upon all that moveth upon the earth, and upon all the fishes of the sea; into your hand are they delivered. Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things. But flesh with the life thereof, which is the blood thereof, shall ye not eat."
Genesis 9:2-4, KJV
Note: In the following verses, the words "meat" and "meats" are not actually referring to meat, such as beef, chicken, etc. Derived from the Greek words "broma" and "brosis", they refer to food and eating in general. The word "flesh", however, is derived from the Greek word "kreas", which signifies the flesh of a sacrificed animal.
"And he called the multitude, and said unto them, Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man."
Matthew 15:10-11, KJV
"On the morrow, as they went on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray about the sixth hour: And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, And saw heaven opened, and a certain vessel descending unto him, as it had been a great sheet knit at the four corners, and let down to the earth: Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air. And there came a voice to him, Rise, Peter; kill, and eat. But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean. And the voice spake unto him again the second time, What God hath cleansed, that call not thou common. This was done thrice: and the vessel was received up again into heaven."
Acts 10:9-16, KJV
"Him that is weak in the faith receive ye, but not to doubtful disputations. For one believeth that he may eat all things: another, who is weak, eateth herbs. Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him . . . I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean. But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died. Let not then your good be evil spoken of: For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost . . . For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence. It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak. Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth. And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin. We then that are strong ought to bear the infirmities of the weak, and not to please ourselves. Let every one of us please his neighbour for his good to edification. For even Christ pleased not himself; but, as it is written, The reproaches of them that reproached thee fell on me."
Romans 14:1-3, 14-17, 20-23, 15:1-3, KJV
"Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; Speaking lies in hypocrisy; having their conscience seared with a hot iron; Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth."
1 Timothy 4:1-3, KJV
