'Mourner' in the Bible

Come hath the time, arrived hath the day, The buyer doth not rejoice, And the seller doth not become a mourner, For wrath is unto all its multitude.

The king doth become a mourner, And a prince putteth on desolation, And the hands of the people of the land are troubled, From their own way I deal with them, And with their own judgments I judge them, And they have known that I am Jehovah!'
