“…And I will set My glory among the heathen, and all the heathen shall see My judgment that I have executed, and My hand that I have laid upon them.  So the house of Israel shall know that I am the LORD their God from that day and forward.  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.  According to their uncleanness and according to their transgressions have I done unto them, and hid My face from them.”
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 jealous for My holy name; after that they have borne their shame, and all their trespasses whereby they have trespassed against Me, when they dwelt safely in their land, and none made them afraid.  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; 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.  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.
