'Night' in the Bible

Let thine ear now be attentive, and thine eyes open, that thou mayest hearken unto the prayer of thy servant, which I pray before thee at this time, day and night, for the children of Israel thy servants while I confess the sins of the children of Israel, which we have sinned against thee. Yea, I and my father's house have sinned:

And I arose in the night, I and some few men with me; neither told I any man what my God put into my heart to do for Jerusalem; neither was there any beast with me, save the beast that I rode upon.

And I went out by night by the valley gate, even toward the jackal's well, and to the dung gate, and viewed the walls of Jerusalem, which were broken down, and the gates thereof were consumed with fire.

Then went I up in the night by the brook, and viewed the wall; and I turned back, and entered by the valley gate, and so returned.

But we made our prayer unto our God, and set a watch against them day and night, because of them.

Likewise at the same time said I unto the people, Let every one with his servant lodge within Jerusalem, that in the night they may be a guard to us, and may labor in the day.

And I went unto the house of Shemaiah the son of Delaiah the son of Mehetabel, who was shut up; and he said, Let us meet together in the house of God, within the temple, and let us shut the doors of the temple: for they will come to slay thee; yea, in the night will they come to slay thee.

Moreover in a pillar of cloud thou leddest them by day; and in a pillar of fire by night, to give them light in the way wherein they should go.

yet thou in thy manifold mercies forsookest them not in the wilderness: the pillar of cloud departed not from over them by day, to lead them in the way; neither the pillar of fire by night, to show them light, and the way wherein they should go.
