'Nights' in the Bible

and [after he] had fasted forty days and forty nights, then he was hungry.

For just as Jonah was in the belly of the huge fish three days and three nights, so the Son of Man will be in the heart of the earth three days and three nights.

So [throughout] the days he was teaching in the temple [courts], and [throughout] the nights he was going out [and] spending the night on the hill that is called [the Mount] of Olives.

in beatings, in prisons, in disturbances, in troubles, in sleepless nights, in going hungry,

with toil and hardship, often in sleepless nights, with hunger and thirst, often going hungry, in cold and poorly clothed.
