מדרש על בראשית 24:43

Rabbi 'Aḳiba said: Anyone who enters a city, and finds maidens coming forth before him, his way will be prosperous (before him). Whence dost thou know this? Know that it is so. Come and see from Eliezer, the servant of our father Abraham, who, whilst he had not yet entered the city, found maidens coming out before him, as it is said, "Behold, I stand by the fountain of water," etc. (Gen. 24:43). And He prospered his way.
