'Mourning' in the Bible

Therefore thus saith Jehovah, the God of hosts, the Lord: Wailing shall be in all the broad ways; and they shall say in all the streets, Alas! Alas! and they shall call the husbandman to mourning, and such as are skilful in lamentation to wailing.

And I will turn your feasts into mourning, and all your songs into lamentation; and I will bring sackcloth upon all loins, and baldness upon every head; and I will make it as the mourning for an only son, and the end thereof as a bitter day.
