'Deny' in the Bible

Then he told all of them, "If anyone wants to come with me, he must deny himself, pick up his cross every day, and follow me continuously,

But Jesus said, "I tell you, Peter, the rooster will not crow today until you deny three times that you know me."

Then the Lord turned and looked straight at Peter. And Peter remembered the word from the Lord, and how he had told him, "Before a rooster crows today, you will deny me three times."
