Jeremiah 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith YHWH, 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.
The Fulfillment of the Promise
Hebrews 10:16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts and in their minds will I write them; 17 And their sins and iniquities will I remember no more. 18 Now where remission of these is, there is no more offering for sin.
8:10 For this is the covenant that I will make with the house of
Israel after those days, saith the Lord; I will put my laws
into their mind, and write them in their hearts:
and I will be to them a God, and they shall be to me a people: 11 And they
shall not teach every man his neighbour, and every man his brother, saying,
Know the Lord: for all shall know me, from the least to the greatest. 12
For I will be merciful to their unrighteousness, and their sins and their
iniquities will I remember no more.
YHWH’s Law is the 10 Commandments spoken from the mountain in Exodus 20.
