'Affirmation' in the Bible

Lo, I am against thee, An affirmation of Jehovah of Hosts, And I have burned in smoke its chariot, And thy young lions consume doth a sword, And I have cut off from the land thy prey, And not heard any more is the voice of thy messengers!

Lo, I am against thee, An affirmation of Jehovah of Hosts, And have removed thy skirts before thy face, And have shewed nations thy nakedness, And kingdoms thy shame,
