'Proof' in the Bible

"Again it is written," replied Jesus, "'Thou shalt not put the Lord thy God to the proof.'"

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."

Then came some of the Pharisees to Him to put Him to the proof by the question, "Has a man a right to divorce his wife whenever he chooses?"
