For I will take you from among the heathen,
and gather you out of all countries,
and will bring you into your own land.
Then will I sprinkle clean water upon you,
and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
A new heart also will I give you,
and a new ruach will I put within you:
and I will take away the stony heart out of your flesh,
and I will give you a heart of flesh.
And I will put my Ruach within you,
and cause you את to walk in my statutes,
and ye shall guard my judgments,
and do them.
And ye shall dwell in the land that I gave to your fathers;
and ye shall be my people, and I will be your Elohiym.
Yechezq'el (Ezekiel) 36:24-28

Jubilees 1:22-23
[22]And after this they will turn to Me in all uprightness and with all (their) heart and with all (their) soul,
and I will circumcise the foreskin of their heart and the foreskin of the heart of their seed,
and I will create in them a holy spirit,
and I will cleanse them so that they shall not turn away from Me from that day unto eternity.
[23]And their souls will cleave to Me and to all My commandments,
and they will fulfil My commandments,
and I will be their Father and they shall be My children.
