'Nights' in the Bible

After he fasted forty days and forty nights he was famished.

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

in beatings, in imprisonments, in riots, in troubles, in sleepless nights, in hunger,

in hard work and toil, through many sleepless nights, in hunger and thirst, many times without food, in cold and without enough clothing.
