'Night' in the Bible

This book of the law shall not depart out of thy mouth, but thou shalt meditate thereon day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.

and command ye them, saying, Take you hence out of the midst of the Jordan, out of the place where the priests feet stood firm, twelve stones, and carry them over with you, and lay them down in the lodging-place, where ye shall lodge this night.

So Joshua arose, and all the people of war, to go up to Ai: and Joshua chose out thirty thousand men, the mighty men of valor, and sent them forth by night.

And Joshua sent them forth; and they went to the ambushment, and abode between Beth-el and Ai, on the west side of Ai: but Joshua lodged that night among the people.

So they set the people, even all the host that was on the north of the city, and their liers-in-wait that were on the west of the city; and Joshua went that night into the midst of the valley.

Joshua therefore came upon them suddenly; for he went up from Gilgal all the night.
