Genesis 3:1-5 Now the serpent was more cunning than any beast of the field which the LORD God had made. And he said to the woman, "Has God indeed said, "You shall not eat of every tree of the garden"?" And the woman said to the serpent, "We may eat the fruit of the trees of the garden; but of the fruit of the tree which is in the midst of the garden, God has said, "You shall not eat it, nor shall you touch it, lest you die."" Then the serpent said to the woman, "You will not surely die. For God knows that in the day you eat of it your eyes will be opened, and you will be like God, knowing good and evil."

John 20:24-29 Now Thomas, called the Twin, one of the twelve, was not with them when Jesus came. The other disciples therefore said to him, 'We have seen the Lord.' So he said to them, 'Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe.' And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, “Peace to you!” Then He said to Thomas, “Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.” And Thomas answered and said to Him, "My Lord and my God!" Jesus said to him, "Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed."
