13 Let no one say when he is tempted, “I am tempted by God,” for God cannot be tempted by evil, and he himself tempts no one. 14 But each one is tempted when he is lured and enticed by his own desires. 15 Then when desire conceives, it gives birth to sin, and when sin is full grown, it gives birth to death. 16 Do not be led astray, my dear brothers and sisters. 17 All generous giving and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or the slightest hint of change. 18 By his sovereign plan he gave us birth through the message of truth, that we would be a kind of firstfruits of all he created.

Rava said: Initially, the verse called the evil inclination a traveler coming from afar. Subsequently, the verse calls it a guest, as one welcomes it. Ultimately, the verse calls it man, indicating significance, as it became the homeowner. As it is stated in the parable of the poor man’s lamb that Nathan the prophet said to David: “And there came a traveler to the rich man, and he was reluctant to take of his own flock and of his own herd, to prepare for the guest” (II Samuel 12:4). And it is written in the same verse: “And he took the poor man’s lamb, and prepared it for the man that was come to him.” In other words, the evil inclination that began as a traveler gradually rose in prominence.
