The fig, the olive, Mount Sinai, and the sacred city of Makkah are mentioned together in association in xcv. 1-3, where we shall consider its meaning. Olive oil is an ingredient in medicinal ointments. If used for food, the olive has a delicious flavour, Cf. also xxiv. 35, where the olive is called a Blessed Tree, and n. 3000.
