'All night' in the Bible

And they took up Asahel, and buried him in the sepulcher of his father, which was in Bethlehem. And Joab and his men went all night, and the day broke upon them at Hebron.

Now when they came into the house, as he lay on his bed in his bedchamber, they smote him, and killed him, and beheaded him, and took his head, and went by the way of the Arabah all night.

David therefore besought God for the child. And David fasted, and went in, and lay all night upon the ground.
