Baruch 4:1
1 She is the book of the commandments of God, the law that endures forever. All who hold her fast will live, and those who forsake her will die. 2 Turn, O Jacob, and take her; walk toward the shining of her light. 3 Do not give your glory to another, or your advantages to an alien people. 4 Happy are we, O Israel, for we know what is pleasing to God.
Matthew 5:18
17 “Do not think that I have come to abolish the law or the prophets. I have not come to abolish these things but to fulfill them. 18 I tell you the truth, until heaven and earth pass away not the smallest letter or stroke of a letter will pass from the law until everything takes place. 19 So anyone who breaks one of the least of these commands and teaches others to do so will be called least in the kingdom of heaven, but whoever obeys them and teaches others to do so will be called great in the kingdom of heaven. 20 For I tell you, unless your righteousness goes beyond that of the experts in the law and the Pharisees, you will never enter the kingdom of heaven!

In Enoch 99:2, it is the 'eternal law' ..."
