'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.

He also stripped [off] his clothes and prophesied before Samuel. He lay naked all that day and all night. Therefore they say, "[Is] Saul also among the prophets?"

{Then Saul immediately fell prostrate} to the ground, and he was very afraid because of the words of Samuel; there was no more strength in him, for he had not eaten food all day and 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.
