'All night' in the Bible

I repent that I have set up Saul to be king: for he is turned back from following me, and hath not performed my commandments. And it grieved Samuel; and he cried to 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 Beth-shan, and came to Jabesh, and burnt them there.
