And they shall know that I am Jehovah: I have not said in vain that I would do this evil unto them.

And they will be certain that I am the Lord: not for nothing did I say that I would do this evil to them.

Και θελουσι γνωρισει οτι εγω ο Κυριος δεν ελαλησα ματαιως, οτι ηθελον καμει εις αυτους τα κακα ταυτα.

And they shall know that I am the Lord, and that I have not said in vain that I would do this evil unto them.
