Ezekiel 39,23-29
23 And the heathen shall know that the house of Israel went into captivity for their iniquity: because they trespassed against me, therefore hid I my face from them, and gave them into the hand of their enemies: so fell they all by the sword.
24 According to their uncleanness and according to their transgressions have I done unto them, and hid my face from them.
25 Therefore thus saith the Lord GOD; Now will I bring again the captivity of Jacob, and have mercy upon the whole house of Israel, and will be jeualous for my holy name;
26 After that they have borne their shame, and all theffdir trespasses whereby they have trespassed against me, when they dwelt safely in their land, and none made them afraid.
27 When I have brought them again from the people, and gathered them out of their enemies' lands, and am sanctified in them in the sight of many nations;
28 Then shall they know that I am the LORD their God, which caused them to be led into captivity among the heathen: but I have gathered them unto their own land, and have left none of them any more there.
29 Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.

Isaiah 65;1-8
1 I am sought of them that asked not for me; I am found of them that sought me not: I said, Behold me, behold me, unto a nation that was not called by my name.
2 I have spread out my hands all the day unto a rebellious people, which walketh in a way that was not good, after their own thoughts;
3 A people that provoketh me to anger continually to my face; that sacrificeth in gardens, and burneth incense upon altars of brick;
4 Which remain among the graves, and lodge in the monuments, which eat swine's flesh, and broth of abominable things is in their vessels;
5 Which say, Stand by thyself, come not near to me; for I am holier than thou. These are a smoke in my nose, a fire that burneth all the day.
6 Behold, it is written before me: I will not keep silence, but will recompense, even recompense into their bosom,
7 Your iniquities, and the iniquities of your fathers together, saith the LORD, which have burned incense upon the mountains, and blasphemed me upon the hills: therefore will I measure their former work into their bosom.
8 Thus saith the LORD, As the new wine is found in the cluster, and one saith, Destroy it not; for a blessing is in it: so will I do for my servants' sakes, that I may not destroy them all.

Psalms 147;19-20
19 He sheweth his word unto Jacob, his statutes and his judgments unto Israel.
20 He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the LORD.

2 Esdras 5;23-29
23 And said, O Lord that bearest rule, of every wood of the earth, and of all the trees thereof, thou hast chosen thee one only vine:
24 And of all lands of the whole world thou hast chosen thee one pit: and of all the flowers thereof one lily:
25 And of all the depths of the sea thou hast filled thee one river: and of all builded cities thou hast hallowed Sion unto thyself:
26 And of all the fowls that are created thou hast named thee one dove: and of all the cattle that are made thou hast provided thee one sheep:
27 And among all the multitudes of people thou hast gotten thee one people: and unto this people, whom thou lovedst, thou gavest a law that is approved of all.
28 And now, O Lord, why hast thou given this one people over unto many? and upon the one root hast thou prepared others, and why hast thou scattered thy only one people among many?
29 And they which did gainsay thy promises, and believed not thy covenants, have trodden them down.

Baruch 3:5-11

5Remember not the iniquities of our forefathers: but think upon thy power and thy name now at this time. 6For thou art the Lord our God, and thee, O Lord, will we praise. 7And for this cause thou hast put thy fear in our hearts, to the intent that we should call upon thy name, and praise thee in our captivity: for we have called to mind all the iniquity of our forefathers, that sinned before thee. 8Behold, we are yet this day in our captivity, where thou hast scattered us, for a reproach and a curse, and to be subject to payments, according to all the iniquities of our fathers, which departed from the Lord our God. 9Hear, Israel, the commandments of life: give ear to understand wisdom. 10How happeneth it Israel, that thou art in thine enemies' land, that thou art waxen old in a strange country, that thou art defiled with the dead, 11That thou art counted with them that go down into the grave?
