Isaiah 30:18-19

And therefore will Jehovah wait, that he may be gracious unto you; and therefore will he be exalted, that he may have mercy upon you: for Jehovah is a God of justice; blessed are all they that wait for him. For the people shall dwell in Zion at Jerusalem; thou shalt weep no more; he will surely be gracious unto thee at the voice of thy cry; when he shall hear, he will answer thee.
