21 And they asked him [Jesus], saying, Master, we know that thou sayest and teachest rightly, neither acceptest thou the person of any, but teachest the way of God truly: 22 Is it lawful for us to give tribute unto Caesar, or no? 23 But he perceived their craftiness, and said unto them, Why tempt ye me? 24 Shew me a penny. Whose image and superscription hath it? They answered and said, Caesar's.

25 And he said unto them, Render therefore unto Caesar the things which be Caesar's, and unto God the things which be God's.

26 And they could not take hold of his words before the people: and they marvelled at his answer, and held their peace.

- The Gospel According to Luke, King James Version

And yet people can say "but if we take 'under God' out of the pledge, we'll have to take 'In God We Trust' off our money!" as if it's an argument for having both these phrases.

Although I'd probably consider leaving the country if our money said "In Caesar Bushicus We Trust."
