1 Thessalonians 2:9
Brothers, you remember our labor and toil. We worked night and day so that we would not become a burden to any of you while we proclaimed the gospel of God to you.
The LORD went in front of them by day in a pillar of cloud to lead them along the way, and by night in a pillar of fire to give them light, so they could travel both day and night.
The people stayed up all that day, all that night, and all through the next day, gathering quails. The one who gathered least gathered enough to fill ten omers, as they spread out all around the camp.
1 Chronicles 9:33
These singers, leaders of ancestral households of the descendants of Levi, were living in the chambers of the Temple. Freed from other service responsibilities, they were on duty day and night.
But we prayed to our God. We also set up guards day and night because of them.
Day and night they prowl around its walls; evil and iniquity are within it.
but their plot became known to him. They were even watching the gates day and night to murder him,
He kept screaming night and day among the tombs and on the mountainsides, and kept cutting himself with stones.
So be alert! Remember that for three years, night and day, I never stopped tearfully warning each of you.
2 Thessalonians 3:8
We did not eat anyone's food without paying for it. Instead, with toil and labor we worked night and day in order not to be a burden to any of you.
