Deuteronomy 29:[12] that you may enter into the sworn covenant of the LORD your God, which the LORD your God makes with you this day;
[13] that he may establish you this day as his people, and that he may be your God, as he promised you, and as he swore to your fathers, to Abraham, to Isaac, and to Jacob.

of the word that he commanded, for a thousand generations,

and Israel, for you are my servant;
I formed you, you are my servant;
O Israel, you will not be forgotten by me.

with everlasting salvation;
you shall not be put to shame or confounded
to all eternity.
Isaiah 52:[1] Awake, awake,
put on your strength, O Zion;
put on your beautiful garments,
O Jerusalem, the holy city;
for there shall no more come into you
the uncircumcised and the unclean.
Isaiah 59:[20] "And he will come to Zion as Redeemer,
to those in Jacob who turn from transgression, says the LORD.
[21] "And as for me, this is my covenant with them, says the LORD: my spirit which is upon you, and my words which I have put in your mouth, shall not depart out of your mouth, or out of the mouth of your children, or out of the mouth of your children's children, says the LORD, from this time forth and for evermore."
Isaiah 66:[22] "For as the new heavens and the new earth
which I will make
shall remain before me, says the LORD;
so shall your descendants and your name remain.
