'All night' in the Bible

They retrieved Asahel's body and buried him in his father's tomb at Bethlehem. Then Joab and his men marched all night until daybreak and arrived back in Hebron.

While they were in the house, they struck him, killed him, and cut off his head while he was lying on his bed in his bedroom. They took his head, and traveled all night along the Arabah road.
