Acts 27:33-34

‘And while the day was coming on, Paul besought them all to take some food, saying, “This day is the fourteenth day that you wait and continue fasting, having taken nothing. Wherefore I beseech you to take some food, for this is for your safety, for there will not a hair perish from the head of any of you.” '

Then Paul pointed out that none of them had eaten properly for fourteen days. They had done all that was humanly possible. It was now time to take some food, which would strengthen them for the ordeal ahead. For he promised that not a hair of their heads would perish. This same promise had been given by Jesus when speaking of the tribulations that God's people must face, where it had in mind the need for endurance (Luke 21:18), which again confirms that this story was intended by Luke to have a spiritual application.
