'Mourning' in the Bible

Therefore thus says the Lord God of hosts, the Lord,“There is wailing in all the plazas,And in all the streets they say, ‘Alas! Alas!’They also call the farmer to mourningAnd professional mourners to lamentation.

“Then I will turn your festivals into mourningAnd all your songs into lamentation;And I will bring sackcloth on everyone’s loinsAnd baldness on every head.And I will make it like a time of mourning for an only son,And the end of it will be like a bitter day.
