'All night' in the Bible

It is no longer my pleasure for Saul to be king; for he is turned back from going in my ways, and has not done my orders. And Samuel was very sad, crying to the Lord in prayer all night.

All the fighting men got up and, travelling all night, took Saul's body and the bodies of his sons from the wall of Beth-shan; and they came to Jabesh and had them burned there.
