Matthew 26:72

Then he began to invoke a curse on himself and to swear, "I do not know the man." And immediately the rooster crowed.

He said, "I tell you, Peter, the rooster will not crow this day before you deny three times that you know me."

But Peter said, "Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back some of the price of the land?
