'Yes' in the Bible

She said to him, "Yes, Lord, I have believed that you are the Christ, the Son of God, who comes into the world."

Now when they had eaten breakfast, Jesus said to Simon Peter, "Simon [son] of John, do you love me more than these?" He said to him, "Yes, Lord, you know that I love you." He said to him, "Feed my lambs!"

He said to him again a second time, "Simon [son] of John, do you love me?" He said to him, "Yes, Lord, you know that I love you." He said to him, "Shepherd my sheep!"
