What did jesus meant when he said "Thou shall not kill"?

Well you're taking the word killing too literal. In the new testiment Jesus explains that to kill doesn't only mean killing someone literally but it also means to tell lies about them, you know like gossiping. To kill can also mean making another christian fall in to their temptations by flirting, or dressing in a provocative way.

and what you are talking about is way off context because back in the day people killed animals as a sacrafice to God. Animals were put on this earth to feed us. Even Jesus ate meat so that has nothing to do with what Jesus was saying.

i hope this helps you out and maybe reading some of the gospels like mathew, mark, luke and john could help you too becuase Jesus does break down the ten commandments further because the religious leaders would ask him a lot about the ten commandments because they felt he was following them

Biblical killing in the old covenant was distinguished by lawful and unlawful. In the new covenant, Yahshua has brought in a new priesthood. The basis of this Way, if charity, forgiveness and mercy. There is no lawful way or reason to kill another human being in true Christianity. Even dying on the pole, He said, 'Father, forgive them, for they know not what they do." As Christians, we are suppose to know what we are doing and have no more reasons for behaving like Cain ever again. We are our brothers keepers.

As far as animals and birds, there is nothing spoken of concerning anything other than a kosher diet which can and does include certain meats.

The word Kill is not the same meaning as Murder.

Thou shalt not Murder. a commandment

Murder is between Humans and selfish motives. and a sin.

Kill is for anything that lives, food is to be killed to live, its Gods design while this earth is still in existance.

If you Kill a human its murder, if not for protection.

He meant exactly what he said, "don't kill"=)

I am referring you to the following:

The commandment "thou shall not kill" (Exodus 20:13; Deuteronomy 5:17), is better understood to mean "you shall not murder." Most modern translations of the Bible rendered it this way.

According to the Bible not all killing, the taking of a life, is murder. Murder is the unlawfully taking of human life. The command not to murder applies to human beings, not to killing animals or plant life for food. God gave animals to mankind for his use (Genesis 1:26-30; 9:1-4). But, this does not mean that humans have the right mistreat animals and the environment (Genesis 2:15; Deuteronomy 22:6-7; 25:4; Proverbs 12:10).

Under the Old Covenant God allowed the Israelites to kill other humans under very special circumstances such as punishment for certain sins, for example, murder (Exodus 21:12-14, Leviticus 24:17, 21) and adultery (Leviticus 20:10, Deuteronomy 22:22-24). God also allowed the Israelites to engage in warfare and even gave them instructions about waging war (Deuteronomy 20:1-20). God also recognized that humans might accidentally kill each other, and he made provisions for this (Numbers 35:9-34; Deuteronomy 19:1-13).

The primary reason God hates murder is that out of all creation, only human are made in the image of God (Genesis 1:26-27; 9:4-6). Even before the codification of the Ten Commandments at Mount Sinai the murder of other human beings was wrong (Genesis 4:8-12; 4:23-24; 9:4-6; Exodus 1:16-17). While on earth, Jesus spoke out against murder (Matthew 5:21-26; Mark 10:17-19). We also see in the writings of Paul (Romans 1:18, 29-32; 13:8-10; Galatians 5:19-21), James (James 2:8-11; 4:1-3), Peter (1 Peter 4:15-16) and John (Revelation 9:20-21; 21:7-8; 22:14-15) that murder is wrong.

In Matthew 5:21-26 Jesus amplifies the meaning of the sixth commandment. He brings out that to commit murder means more then just killing someone, it means having an angry and unforgiving attitude towards them:

"You have heard that it was said to those of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’ But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, ‘Raca!’ shall be in danger of the council. But whoever says, ‘You fool!’ shall be in danger of hell fire. (More at the Link above)

He meant "thou shall not kill unless whoever you're killing doesn't believe in me, that is, after you've tried torturing him into conversion."

My Dear Sweet Friends,

The commandment need not be interpreted. It mean just what it said. However, to sustain life we must kill. Therefore it is incumbent upon us to bless that which we eat.

Topgunner and Notsocrazieme both got it right!
