Why Was the Law Given to Israel
“In this case, the master should take his servant. to God, that is, to the place where the judgment was pronounced in the name of God [cf. Deuteronomy 1:17; 19:17; cf. Exodus 22:7-8] so that he could declare that he had renounced his freedom. His ear was then to be pierced with a punch against the door or lintel of the house and attached to the house forever by this sign, which was usual among many peoples of antiquity. That it is the meaning of piercing the ear against the door of the house is evident in the unusual expression in [Deuteronomy 15:17]: “And put (the hallmark) in his ear and in the door, that he may be your servant forever,” where the ear and the door are coordinated. (Keil and Delitzsch, commentary, 1:2:130.) There are respected Christian teachers who consider the Mosaic Law to be the rule of life for Christians today.1 One view often found among sincere Orthodox believers is that, although we are not saved by the law, the Mosaic Law becomes our rule of life once we have been justified by faith. Those who have such a view usually make a clear division of the Mosaic law into two parts, which distinguish them as moral and ceremonial. They regard the ceremonial part as fulfilled in Christ at His first coming and therefore as now dead. But the moral part of the Mosaic law, they say, is still in force as the rule of the believer`s life.
The treatment of Christian ethics by some highly respected authors is, in fact, little more than an account of the Decalogue. (2) The law was given to identify sin and to reveal man`s sin and bankruptcy as guilty before God (Romans 3:19f; 7:7-8; 5:20; Galatians 3:19). God`s holy law reveals to man who and what he is – sinful and separated from God by an infinite gulf that he cannot fill with his own human strength. When was the law proclaimed? “. until the offspring came, to whom the promise had been made. (Gal 3:19b) The Mosaic law is what concerns us most about the New Testament believer. There were 365 negative orders and 248 positive orders for a total of 613 orders. These can also be divided into three parts or sections (see below) – moral, social, and ceremonial. As such, it covered every possible area of Israel`s life. It should be emphasized that the moral principles embodied in the Mosaic law given at Sinai were merely the codified expression of God`s eternal moral law, as it was given to Israel to govern its life as a nation, to experience God`s blessing under the Abrahamic covenant.
You can find more information on this aspect below. Why was the law passed? “It was added for transgressions… (Galatians 3:19a). By keeping the law, we are talking about true meaning as God intended, not as Israel and people tend to accept it. The Ten Commandments showed the Jew his sin (and therefore all mankind) and that he was trapped under that sin. The Ten Commandments were intended to guide him, even to lead him to the ceremonial law (tabernacle, priesthood, and sacrifice) in order to obtain forgiveness by faith in the sacrifices that pointed to Christ. Second, social law regulated his life by showing him how to live socially, not to give him merit before God, but to enable him to experience the blessings of the covenant, rather than the curse, as God warned in Deuteronomy. The instructions given to Israel ensured that she was not forced into a relationship she did not understand or want. After Israel expressed its willingness to receive the Law and swore to live it, Moses was free to act for Israel in the presence of the Lord. No Israelite was ever saved by keeping the law of Moses. No obedience could make them righteous before God. (Romans 3:20) Since the law could not save, why did God give the law to Israel? There is much speculation about the purpose of the law, but speculation is not necessary. The Bible gives several specific reasons why the law was given.
The law was given to tighten the screws on people`s sins so that they could cry out for a deliverer in fear. These specific laws further clarify the commandments or basic principles. Thus, God`s law is His system of rules by which He shows and instructs His will and administers the affairs of the world. Obviously, the definition allows and implies that there may be different systems of rules at different times, depending on the particular aspects or amount of His will that God wants to show at any given time. A system of rules can be tailor-made for different moments, peoples or objectives. 6 But it must be understood at once that this does not mean that we must necessarily behave in a manner contrary to what the Mosaic law commands: that we must kill, steal, bear false witness, etc. Long before the law was given by Moses, it was completely wrong to do such bad things.2 Although the term “law” was never used specifically for Adam and Eve`s relationship with God in the garden, according to the definition of “law,” a system of principles or rules that teaches man God`s will and direction, there was a law given to Adam. He was ordered to “clothe and guard” the garden and eat free of all trees except “the tree of the knowledge of good and evil.” The law of Moses was given as a schoolmaster or educator to bring Israel to Christ. The law was given to help us realize that we were imprisoned, and the only way out of prison is grace available through the promise of faith.
The Mishnah reports that during the Second Temple period, the Ten Commandments were recited daily, before the reading of the Shema Yisrael (as preserved, for example, in the Nash Papyrus, a Hebrew manuscript fragment from 150-100 BC found in Egypt that contains a version of the Ten Commandments and the beginning of the Shema); but that this practice was abolished in synagogues so as not to give ammunition to heretics who claimed to be the only important part of Jewish law, or to dispel an early Christian claim that only the Ten Commandments and not the entire Torah were transmitted to Mount Sinai.  How was the law given? “. and it was established by angels from an intermediary.” It is customary to divide the Mosaic law into three parts, as shown below, but while it is useful for the analysis and study of the Mosaic law and how it works, such a division is never stated as such in Scripture. Rather, it is considered a unit. The arguments in favor of this are given below. The Ten Commandments are a summary of the requirements of a covenant (called the “Old Covenant”) given on Mount Sinai to the nascent nation of Israel. [ref. needed] The Old Covenant ended on the cross and is therefore not effective.
[ref. needed] They reflect God`s eternal character and serve as a model of morality.  In these verses we read Paul`s explanation of why the law was given.
