'All night' in the Bible

It grieves me that I have set up Saul to be king: for he has turned back from following me, and has not performed my commandments. And it grieved Samuel; and he cried unto the LORD all night.

All the valiant men arose, and went all night, and took the body of Saul and the bodies of his sons from the wall of Bethshan, and came to Jabesh, and burnt them there.
