'Proof' in the Bible
Then Jesus told him, "See to it that you don't speak to anyone. Instead, go and show yourself to the priest, and then offer the sacrifice that Moses commanded as proof to the authorities."
He told the man, "Be sure that you don't tell anyone. Instead, go and show yourself to the priest, and then offer for your cleansing what Moses commanded as proof to the authorities."
Then Jesus ordered him, "Don't tell anyone. Instead, go and show yourself to the priest and make an offering for your cleansing, just as Moses commanded, as proof to the authorities."
because he has set a day when he is going to judge the world with justice through a man whom he has appointed. He has given proof of this to everyone by raising him from the dead."
since you want proof that the Messiah is speaking through me. He is not weak in dealing with you but is making his power felt among you.
Do you want proof, you foolish person, that faith without actions is worthless?
