Deuteronomy 32:9
[9]For the LORD'S portion is his people; Jacob is the lot of his inheritance.
Jubilees 15:28-32
[28]And do thou command the children of Israel and let them observe the sign of this covenant for their generations as an eternal ordinance, and they will not be rooted out of the land.
[29]For the command is ordained for a covenant, that they should observe it for ever among all the children of Israel.
[30]For Ishmael and his sons and his brothers and Esau, the Lord did not cause to approach Him, and he chose them not because they are the children of Abraham, because He knew them, but He chose Israel to be His people.
[31]And He sanctified it, and gathered it from amongst all the children of men; for there are many nations and many peoples, and all are His, and over all hath He placed spirits in authority to lead them astray from Him.
[32]But over Israel He did not appoint any angel or spirit, for He alone is their ruler, and He will preserve them and require them at the hand of His angels and His spirits, and at the hand of all His powers in order that He may preserve them and bless them, and that they may be His and He may be theirs from henceforth for ever.
2 Esdras 7:10-14
[10]And I said, It is so, Lord. Then said he unto me, Even so also is Israel's portion.
[11]Because for their sakes I made the world: and when Adam transgressed my statutes, then was decreed that now is done.
[12]Then were the entrances of this world made narrow, full of sorrow and travail: they are but few and evil, full of perils,: and very painful.
[13]For the entrances of the elder world were wide and sure, and brought immortal fruit.
[14]If then they that live labour not to enter these strait and vain things, they can never receive those that are laid up for them.
