R. Eliezer b. Yaakov says: The Holy Spirit reposed upon them and he (a Jew) would say: Lend me your vessel which is found in this and this place, and he (the Egyptian) would find it there and give it to him. "chen" ("favor") is the Holy Spirit, as it is written (Zechariah 12:10) "And I will pour out on the house of David and on the dwellers on Jerusalem a spirit of chen, etc."
