^y“Behold, the days are coming, declares the Lord,
when I will establish a new covenant with the house of Israel

For they did not continue in my covenant,
and so I showed no concern for them, declares the Lord.
10 ^zFor this is the covenant that I will make with the house of Israel
after those days, declares the Lord:
I will put my laws into their minds,
and ^aawrite them on their hearts,
and I will be their God,
and they shall be my people.
