“They said therefore vnto him, What signe shewest thou then, that we may see, and beleeue thee? What doest thou worke?”
1611 King James Version (KJV)
6:30 What sign dost thou? - Amazing, after what they had just seen!
Joh 6:30 What sign shewest thou then, that we may see, and believe thee? He had pointed to himself as the object of faith, making his claim, such as had never been made by mortal man. He had spoken of his seal, or sign. They ask now for a sign.
