It was one of the most valuable products of the country (Deuteronomy 32:13; Ezekiel 16:13 ), and formed an article of extensive commerce with Tyre (27:17).
The use of it was a sign of gladness (Psalm 92:10; Isaiah 61:3 ), and its omission a token of sorrow (2 Samuel 14:2; Matthew 6:17 ). It was very abundant in Galilee. (See OLIVE .)
