Does the Bible say, “Depart from me, you who practice the law”?
NO! It says the following:
Matthew 7:22. Many will say to me in that day, “My master, my master. By your name, have we not prophesied? And by you name have we cast out demons? And by your name have we done many miracles?” 23. And then I will profess to them that from everlasting, I have not known you. Depart from me, you workers of iniquity! 
24. Anyone, therefore, who hears my words, these, and does them, will be likened to a wise man who built his house upon a stone. 25. And descended the rain, and came the rivers, and blew the winds, and they beat on the house and it did not fall, for its foundation was laid upon a stone.
26. And anyone who hears my words, these, and does them not, will be likened to a foolish man that built his house upon sand. 27. And descended the rain, and came the rivers, and blew the winds, and they beat on the house and it fell, and its fall was great. 28. And it happened that when Y’shua finished these words, the crowds marveled at his teaching. 29. He would teach for them as an authority,  and not as their scribes and the Pharisees. (AENT)
 Psalm 6:8, 9 ‑ “workers of iniquity” is a common phrase in the Tanakh. Iniquity is lawlessness (without Torah). “Horror has taken hold upon me because of the wicked that forsake Your Torah.” Psalm 119:53. Each and every teaching of Y’shua is based on Torah. To be anti-Torah is to be anti-Mashiyach; therefore every “authority” will be judged according to whether they uphold Torah or not. According to Y’shua, Torah is “the will of My Father.” Matthew 7:21;12:50. Torah means instruction in righteousness.
 The Pharisees and scribes both appealed to the authority of oral traditions that were handed down from their teachers of the past, eventually these traditions became codified as the Talmud. However, Y’shua’s authority as the Son of Man was squarely on the Written Torah and YHWH’s Prophets. Y’shua clearly encouraged the great rabbis of his day to study and apply Torah as a lifestyle (righteous conduct).
Had the Pharisees studied Torah and the Prophets with and through Mashiyach, it would have brought them around to the same halachic, or legal positions Y’shua taught his disciples. Contrary to religious opinion Y’shua taught the Government of YHWH (righteous spirituality and conduct) rather than a new or different religion.
QUESTION: Does the passage above sound like God's original teaching and instruction were somehow abolished?
Yeshua's intent was not to abolish or weaken or emasculate the Laws of YHWH, revealed in the Old Testament, but to expand and magnify them to their full spiritual intent and conclusion; to show their full meaning, purpose, and relevance; to reveal their spiritual and supernatural nature and basis; to show that the commandments lead us by necessity to FAITH in him as the Messiah.
We do not earn salvation by works, but by Faith in Yeshua the Messiah, who died for our sins, and who now gives us his spirit to enable us to fulfill the righteousness of the Law (Acts 2:38; 5:32; Gal.2:20).
The Messiah did not replace the Law of YHWH with Faith alone; but rather gave us inward Faith, through his spirit, to enable us to observe the holy commandments of God! Yet, unfortunately, with the advent of other “religions”, Torah (YHWH’s Divine Instructions in Righteousness) and the rest of the "Old Testament", basically became null and void because people mistakenly believe "Torah" equates to "law", and that the death of Jesus negated the law….
The apostle Paul knew this truth and wrote to the believers in Rome:
Romans3:31 Do, we then nullify Torah by faith? May it never be! On the contrary, we establish Torah.
Not one yud or stroke ("jot or tittle") was abolished from the Torah … and won’t be, until everything that must happen has happened. (See Matthew 5:17-20.)
