KJV:
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.
NASB:
"Then they will know that I am the LORD their God because I made them go into exile among the nations, and then gathered them again to their own land; and I will leave none of them there any longer.
