'Permitted' in the Bible

The Pharisees said to Him, “Look, why are they doing what is unlawful on the Sabbath?”

how he went into the house of God in the time of Abiathar the high priest, and ate the sacred bread, which is not lawful for anyone but the priests to eat, and how he also gave it to the men who were with him?”

And He allowed no one to go with Him [as witnesses], except Peter and James and John the brother of James.
