Lamentations 2:19

The prophet calls upon the Jews not to be slothful in this their very evil day, but to rise up from their beds, and either at the beginning of the four watches, or at the beginning of each watch, at all times in the night, to betake themselves to God by prayer, and that not in a cold, lazy manner, but so as to pour out their hearts with their words; and he moveth them to it, as for their own sake, so for the sake of their young children, who every where were starved to death.
