The Law that was given for transgression wasn't the Torah. It was the Mosaic Covenant, to include the Tabernacle Law. The first time Moses went up to the Mountain he only received the Torah. The second time he received the Law of the Tabernacle.
Jer 7:22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices:
Jer 7:23 But this thing commanded I them, saying, Obey my voice, and I will be your God, and ye shall be my people: and walk ye in all the ways that I have commanded you, that it may be well unto you.
It was the sacrifices and burnt offerings that were added.
The Torah, including the ordinances, are forever for all Israel. If you believe in Messiah, you ARE Israel.
Jer 31:31 Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
Jer 31:32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
Jer 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
Jer 31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
Jer 31:35 Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name:
Jer 31:36 If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever.
Eph 2:11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
Eph 2:12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
Eph 2:13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
Yeshayahu 9:7 Of the increase of His rule and peace there is no end, upon the throne of David and over His reign, to establish it and sustain it with justice and with righteousness from now on, even forever. The ardour of יהוה of hosts does this.
