The ten commandments are shown on two tablets. There is a correspondence between the first five and the second five.
The first commandment is to Know that there is Gd, who took us out of the land of Egypt to be Gd to us. This commandment is for us to know that all the glory in the world is He and that He glorifies us with life in order to have a relationship with Him. He took us out of the lowest level – a position of slavery, idolatry, and suffering – in order to give Torah and mitzvahs to us and for us to have a relationship, a loving relationship with Him.
The sixth commandment is Do Not Kill. The Torah goes through all the scenarios that are permitted, such as self-defense.
The correlation is that man is made in the image of Hashem. Each person is a universe, a being with a spark of holiness here to accomplish a positive expression for Hashem as well as to repair something. Yet we are in bodies that are imperfect and drawn to competing interests, and this is by design. Each of us has, in every moment, the opportunity to decide if we will conduct ourselves as made in Hashem’s Image or according to our lower urges, including survival instincts, ego goals, desires, arrogance, angers, fears, yearning for honor, greed and more.
Without Torah, we would not have a guide to tell us what pitfalls to watch out for. The major religions of the world do not contest that Torah was given by Hashem. It is the basis for the major religions. And the sixth commandment is one of the Noahide Laws, a way of serving Hashem that brings the person eternity, the world to come.
Killing people in a manner that is not permitted by Torah has an inference regarding the first commandment, that people are made in Hashem’s image so that He can have a relationship with us and be Gd to us. How are we having a relationship with Hashem if we are not keeping the sixth commandment regarding killing?
What is and is not permitted is ethical to those who value Torah as absolute truth. When we have a question about what is permitted, we submit our conduct to conform to what we consider to be absolute truth, the Torah. In this way, we serve the first commandment, Know there is Gd Who took us out of Egypt to be Gd to us.
It is important to understand that “going back” to existence as we were before we were given Torah, enslaved, suffering, serving idols, is not permitted. It would make no sense to do so, for all the paths of Torah are peaceful and good, even if we don’t understand how.
The sefira that corresponds to Know there is Gd who took you out of Egypt to be Gd to you is keser, Hashem’s 13 Attributes of mercy. The utterance it corresponds to is Let there be Light. The sefira that corresponds to do not kill is tiferes, compassion. The utterance is Let the waters team with the life and let creatures fly on the face of the sky.
Hashem has created many beings. In anger, or out of hatred, or with a dominating goal that a person believes to be a true value, it is easy to understand how someone can mistakenly kill. But there is a consequence for it. And if the killing is premeditated with subjective goals as a motive, there is a consequence for that too. The life of every person has value, killer and victim. And Hashem will bring every soul to rectification. It is incumbent upon every soul to submit to absolute truth over subjective truths. And if we do not know what the absolute truth is, how can we make a real choice, for if our basis is other than absolute truth, we must consider there could be a mistake and what the consequences for that mistake are and will be.
Human life has value, every person is a creation of Hashem, there is no glory in the world other than Hashem, the place of the world is Hashem and all is known to Hashem.
