“See, the days are coming,” declares יהוה, “when I shall make a renewed covenant with the house of Yisra’ĕl and with the house of Yehuḏah,  not like the covenant I made with their fathers in the day when I strengthened their hand to bring them out of the land of Mitsrayim, My covenant which they broke, though I was a husband to them,” declares יהוה.  “For this is the covenant I shall make with the house of Yisra’ĕl after those days, declares יהוה: I shall put My Torah in their inward parts, and write it on their hearts. And I shall be their Elohim, and they shall be My people.  “And no longer shall they teach, each one his neighbour, and each one his brother, saying, ‘Know יהוה,’ for they shall all know Me, from the least of them to the greatest of them,” declares יהוה. “For I shall forgive their crookedness, and remember their sin no more.” (Jeremiah 31:31-34 [TS2009])
Oh, and don't forget
 * For finding fault with them, He says, “See, the days are coming,” says יהוה, “when I shall conclude with the house of Yisra’ĕl and with the house of Yehuḏah a renewed covenant, *  * not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Mitsrayim, because they did not continue in My covenant, and I disregarded them,” says יהוה. *  * “Because this is the covenant that I shall make with the house of Yisra’ĕl after those days, says יהוה, giving My laws in their mind, and I shall write them on their hearts, and I shall be their Elohim, and they shall be My people. *  * “And they shall by no means teach each one his neighbour, and each one his brother, saying, ‘Know יהוה,’ because they all shall know Me, from the least of them to the greatest of them. *  * “Because I shall forgive their unrighteousness, and their sins and their lawlessnesses I shall no longer remember.” * (Hebrews 8:8-12 [TS2009])
 Let us hear the conclusion of the entire matter: Fear Elohim and guard His commands, for this applies to all mankind!  For Elohim shall bring every work into right-ruling, including all that is hidden, whether good or whether evil. (Ecclesiastes 12:13-14 [TS2009])
And Finally, This
 Anyone who has disregarded the Torah of Mosheh dies without compassion on the witness of two or three witnesses.  How much worse punishment do you think shall he deserve who has trampled the Son of Elohim underfoot, counted the blood of the covenant by which he was set apart as common, and insulted the Spirit of favour?  For we know Him who has said, * “Vengeance is Mine, I shall repay, says יהוה.” * And again, * “יהוה shall judge His people.” *  It is fearsome to fall into the hands of the living Elohim. (Hebrews 10:28-31 [TS2009])
Keep Yehovah's Commandments!
 Do not think that I came to destroy the Torah or the Prophets. I did not come to destroy but to complete.
 For truly, I say to you, till the heaven and the earth pass away, one yod or one tittle shall by no means pass from the Torah till all be done.
 “Whoever, then, breaks one of the least of these commands, and teaches men so, shall be called least in the reign of the heavens; but whoever does and teaches them, he shall be called great in the reign of the heavens.
 For I say to you, that unless your righteousness exceeds that of the scribes and Pharisees, you shall by no means enter into the reign of the heavens.
(Matthew 5:17-20 [TS2009]
