'All night' in the Bible

"I regret that I made Saul king, because he has turned away from following me and has not carried out my commands." Samuel was angry, and he cried out to the LORD all night.

He also removed his clothes and was caught up in prophetic ecstasy right in front of Samuel! He fell down naked and remained there all that day and all night. That is why people say, "Is Saul also among the prophets?"

Saul immediately fell down full-length on the ground. He was terrified because of Samuel's words, and he had no strength because he had not eaten food all day and all night.

every valiant soldier got up, traveled all night, and removed Saul's body and the bodies of his sons from the wall of Beth-shan. Then they went to Jabesh and cremated the bodies there.
