'Night' in the Bible

please let Your ear be attentive and Your eyes open to hear the prayer of Your servant which I am praying before You, day and night, on behalf of Your servants, the sons (descendants) of Israel (Jacob), confessing the sins of the sons of Israel which we have committed against You; I and my father’s house have sinned.

Then I got up in the night, I and a few men with me. I did not tell anyone what my God was putting in my heart to do for Jerusalem, and there was no animal with me except the one on which I was riding [so as not to attract attention].

So I went out at night by the Valley Gate toward the Dragon’s Well and to the Refuse Gate and inspected the walls of Jerusalem which were broken down and its gates which were consumed by fire.

So I went up at night by the ravine [of Kidron] and inspected the wall; then I turned back and entered [the city] by the Valley Gate, and returned.

But we prayed to our God, and because of them we set up a guard against them day and night.

At that time I also said to the people, “Let each man with his servant spend the night inside Jerusalem so that they may serve as a guard for us at night and a laborer during the day.”

When I went into the house of Shemaiah the son of Delaiah, the son of Mehetabel, who was confined at home, he said, “Let us meet [and take refuge] together in the house of God, within the temple, and let us shut the doors of the temple, because they are coming to kill you, and they are coming to kill you at night.”

“And with a pillar of cloud You led them by day,And with a pillar of fire by nightTo light the way for themIn which they were to go.

You, in Your great mercy and compassion,Did not abandon them in the wilderness;The pillar of the cloud did not leave them by day,To lead them in the way,Nor the pillar of fire by night, to light for them the way they should go.
