Lamentations 2.18 ~ River

Their heart cried unto the Lord, 
Just like David's poor man
Who was delivered from trouble.
O wall of the daughter of Zion, 
They wail at your wall yet today.
Let tears run down like a river day and night: 
A desire to hear the word of the Lord
Give thyself no rest; 
Seek him, find him, cry out!
Let not the apple of thine eye cease.
