In November 1943, as they planned a summit meeting, FDR wired Churchill to suggest that Cairo might be too dangerous a location. Churchill responded:

SEE ST. JOHN, CHAPTER 14, VERSES 1 TO 4.

These verses read:

1. Let not your heart be troubled: ye believe in God, believe also in me.
2. In my Father’s house are many mansions; if it were not so, I would have told you, I go to prepare a place for you.
3. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
4. And whither I go ye know, and the way ye know.

They met in Cairo.
