Like the Puritans, the Quakers showed a strong tendency to Biblical names, and Penn had long planned to name his new city for a city mentioned in the New Testament, with a name commonly supposed to mean "brotherly love." And so this location received the name of Philadelphia. And, though the ancient city in Asia Minor mentioned in the Bible was really named for an Egyptian king called "brother-lover" because he assassinated his brother, it is fair to say that the American city is really named for brotherly love, such being obviously the founder's intention.
