'All night' in the Bible

And they took up Asahel, and buried him in the sepulcher of his father, which was in Beth-lehem. And Joab and his men went all night, and they came to Hebron at break of day.

For when they came into the house, he lay on his bed in his bed-chamber, and they smote him, and slew him, and beheaded him, and took his head, and went away through the plain all night.

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