'All night' in the Bible

And they took Asahel's body and put it in the last resting-place of his father in Beth-lehem. And Joab and his men, travelling all night, came to Hebron at dawn.

And when they came into the house, Ish-bosheth was stretched on his bed in his bedroom; and they made an attack on him and put him to death, and, cutting off his head, they took it with them and went by the road through the Arabah all night.

So David made prayer to God for the child; and he took no food day after day, and went in and, stretching himself out on the earth, was there all night.
