Deuteronomy 14:1–21 (NIV)

¹ You are the children of the Lord your God. Do not cut yourselves or shave the front of your heads for the dead, ² for you are a people holy to the Lord your God. Out of all the peoples on the face of the earth, the Lord has chosen you to be his treasured possession. ³ Do not eat any detestable thing. ⁴ These are the animals you may eat: the ox, the sheep, the goat, ⁵the deer, the gazelle, the roe deer, the wild goat, the ibex, the antelope and the mountain sheep. ⁶ You may eat any animal that has a divided hoof and that chews the cud. ⁷ However, of those that chew the cud or that have a divided hoof you may not eat the camel, the rabbit or the hyrax. Although they chew the cud, they do not have a divided hoof; they are ceremonially unclean for you. ⁸ The pig is also unclean; although it has a divided hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses. ⁹ Of all the creatures living in the water, you may eat any that has fins and scales. ¹⁰ But anything that does not have fins and scales you may not eat; for you it is unclean. ¹¹ You may eat any clean bird. ¹² But these you may not eat: the eagle, the vulture, the black vulture, ¹³ the red kite, the black kite, any kind of falcon, ¹⁴ any kind of raven, ¹⁵ the horned owl, the screech owl, the gull, any kind of hawk, ¹⁶ the little owl, the great owl, the white owl, ¹⁷ the desert owl, the osprey, the cormorant, ¹⁸ the stork, any kind of heron, the hoopoe and the bat. ¹⁹ All flying insects are unclean to you; do not eat them. ²⁰ But any winged creature that is clean you may eat. ²¹ Do not eat anything you find already dead. You may give it to the foreigner residing in any of your towns, and they may eat it, or you may sell it to any other foreigner. But you are a people holy to the Lord your God. Do not cook a young goat in its mother’s milk.

Deuteronomy 16:1–8 (NIV)

¹ Observe the month of Aviv and celebrate the Passover of the Lord your God, because in the month of Aviv he brought you out of Egypt by night. ² Sacrifice as the Passover to the Lord your God an animal from your flock or herd at the place the Lord will choose as a dwelling for his Name. ³ Do not eat it with bread made with yeast, but for seven days eat unleavened bread, the bread of affliction, because you left Egypt in haste—so that all the days of your life you may remember the time of your departure from Egypt. ⁴ Let no yeast be found in your possession in all your land for seven days. Do not let any of the meat you sacrifice on the evening of the first day remain until morning. ⁵ You must not sacrifice the Passover in any town the Lord your God gives you ⁶ except in the place he will choose as a dwelling for his Name. There you must sacrifice the Passover in the evening, when the sun goes down, on the anniversary of your departure from Egypt. ⁷ Roast it and eat it at the place the Lord your God will choose. Then in the morning return to your tents. ⁸ For six days eat unleavened bread and on the seventh day hold an assembly to the Lord your God and do no work.

Romans 14:1–23 (NIV)

¹ Accept the one whose faith is weak, without quarreling over disputable matters. ² One person’s faith allows them to eat anything, but another, whose faith is weak, eats only vegetables. ³ The one who eats everything must not treat with contempt the one who does not, and the one who does not eat everything must not judge the one who does, for God has accepted them. ⁴ Who are you to judge someone else’s servant? To their own master, servants stand or fall. And they will stand, for the Lord is able to make them stand. ⁵ One person considers one day more sacred than another; another considers every day alike. Each of them should be fully convinced in their own mind. ⁶ Whoever regards one day as special does so to the Lord. Whoever eats meat does so to the Lord, for they give thanks to God; and whoever abstains does so to the Lord and gives thanks to God. ⁷ For none of us lives for ourselves alone, and none of us dies for ourselves alone. ⁸ If we live, we live for the Lord; and if we die, we die for the Lord. So, whether we live or die, we belong to the Lord. ⁹ For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. ¹⁰ You, then, why do you judge your brother or sister? Or why do you treat them with contempt? For we will all stand before God’s judgment seat. ¹¹ It is written: “ ‘As surely as I live,’ says the Lord, ‘every knee will bow before me; every tongue will acknowledge God.’ ” ¹² So then, each of us will give an account of ourselves to God. ¹³ Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in the way of a brother or sister. ¹⁴ I am convinced, being fully persuaded in the Lord Jesus, that nothing is unclean in itself. But if anyone regards something as unclean, then for that person it is unclean. ¹⁵ If your brother or sister is distressed because of what you eat, you are no longer acting in love. Do not by your eating destroy someone for whom Christ died. ¹⁶ Therefore do not let what you know is good be spoken of as evil. ¹⁷ For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, ¹⁸ because anyone who serves Christ in this way is pleasing to God and receives human approval. ¹⁹ Let us therefore make every effort to do what leads to peace and to mutual edification. ²⁰ Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a person to eat anything that causes someone else to stumble. ²¹ It is better not to eat meat or drink wine or to do anything else that will cause your brother or sister to fall. ²² So whatever you believe about these things keep between yourself and God. Blessed is the one who does not condemn himself by what he approves. ²³ But whoever has doubts is condemned if they eat, because their eating is not from faith; and everything that does not come from faith is sin.
