'Mighty' in the Bible

Yea, come in have many peoples, and mighty nations, To seek Jehovah of Hosts in Jerusalem, And to appease the face of Jehovah.

And I have made mighty the house of Judah, And the house of Joseph I do save, And I have caused them to dwell, for I have loved them, And they have been as if I had not cast them off, For I am Jehovah their God, And I answer them.

And I have made them mighty in Jehovah, And in His name they walk up and down, An affirmation of Jehovah!
