John Lightfoot on Matthew 26:36

[Gethsemane.] The place of the olive presses, at the foot of mount Olivet. In John, it is "a garden beyond Cedron." "They do not make gardens or paradises in Jerusalem, because of the stink. The Gloss, "Because of the stink that riseth from the weeds which are thrown out: besides, it is the custom to dung gardens; and thence comes a stink." Upon this account there were no gardens in the city, (some few gardens of roses excepted, which had been so from the days of the prophets,) but all were without the walls, especially at the foot of Olivet.
