'All night' in the Bible

“I regret that I made Saul king, for he has turned away from following Me and has not carried out My commands.” Samuel was angry [over Saul’s failure] and he cried out to the Lord all night.

Then Saul immediately fell full length on the earth [floor of the medium’s house], and was very afraid because of Samuel’s words; and he was thoroughly exhausted because he had not eaten all day and all night.

all the brave men stood and walked all night, and they took the bodies of Saul and his sons from the wall of Beth-shan, and they came to Jabesh and cremated them there.
