'Nights' in the Bible

After He had fasted 40 days and 40 nights, He was hungry.

For 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.

by beatings, by imprisonments,by riots, by labors,by sleepless nights, by times of hunger,

labor and hardship,many sleepless nights, hunger and thirst,often without food, cold, and lacking clothing.
