'Mourning' in the Bible

Therefore, thus said Jehovah, God of Hosts, the Lord, In all broad places is lamentation, And in all out-places they say, 'Alas, alas,' And called the husbandman to mourning, And to lamentation the skilful of wailing.

And have turned your festivals to mourning, And all your songs to lamentation, And caused sackcloth to come up on all loins, And on every head -- baldness, And made it as a mourning of an only one, And its latter end as a day of bitterness.
