'All night' in the Bible

Then Abner and his men went through the Arabah (desert region) all that night, crossed the Jordan, went through Bithron and walked the whole morning and came to Mahanaim [where Ish-bosheth ruled Israel].

And they picked up [the body of] Asahel and buried him in the tomb of his father in Bethlehem. Then Joab and his men walked all night and they arrived in Hebron at daybreak.

Now when they entered the house he was lying on his bed in his bedroom. They [not only] struck and killed him, [but] they also beheaded him. Then they took his head and traveled all night by way of the Arabah.

David therefore appealed to God for the child [to be healed]; and David fasted and went in and lay all night on the ground.
