Mark 11:19

And every evening he went forth out of the city.

In addition to the reason for Jesus' leaving the city each night and staying either in Bethany or in some secluded place on the slopes of the Mount of Olives, which was cited under the above verse, there was also the evident purpose of our Lord to avoid identification, as much as possible, with any of the places previously accounted sacred. His sitting by Jacob's well (John 4:6) dignified a place not mentioned in the Old Testament, it being nowhere stated therein that Jacob ever dug a well. Nazareth, Cana, Bethany, Bethsaida-Julius, and the majority of the places made memorable by Jesus were simply not identified among the Jews as having any notability. Jesus' refusing to stay all night in Jerusalem was fully compatible with the obvious design of his whole life, which was to show that no place, or person, was so obscure or unimportant as to deny it or him a participation in the mercy which God sent to all.
