Oil

Was employed from the earliest periods in the east, not only for the purpose of consecration, but to anoint the head, the beard, and the whole person in daily life, Genesis 28:18. See ANOINTING. It was also universally used for food, Ezekiel 16:13. Fresh and sweet olive oil was greatly preferred to butter and animal fat as a seasoning for food, and to this day in Syria almost every kind of food is cooked with oil. It had a place also among the meat-offerings in the temple, being usually mixed with the meal of the oblation, Leviticus 5:11 6:21. For lamps, also, pure olive oil was regarded as the best, and was used in illuminating the tabernacle. These many uses for oil made the culture of the olive-tree an extensive and lucrative business, 1 Chronicles 27:28 Ezekiel 27:17 Hosea 12:1. Oil was as much an article of storage and of traffic as corn and wine, 2 Chronicles 32:28 Ezra 3:7.

The best oil was obtained from the fruit while yet green by a slight beating or pressing, Exodus 27:20 29:40. The ripe fruit is now, and has been from ancient times, crushed by passing stone rollers over it. The crushed mass is then subjected to pressure in the oil-mill, Hebrew, gath-shemen. The olive-berries are not now trodden with the feet. This, however seems to have been practiced among the Hebrews, at least to some extent when the berries had become soft by keeping, Micah 6:15. Gethsemane, that is, oil-press, probably took its name originally from some oil-press in its vicinity. See OLIVE.

Oil

Only olive oil seems to have been used among the Hebrews. It was used for many purposes: for anointing the body or the hair (Exodus 29:7; 2Sam 14:2; Psalms 23:5; 92:10; 104:15; Luke 7:46); in some of the offerings (Exodus 29:40; Leviticus 7:12; Numbers 6:15; 15:4), but was excluded from the sin-offering (Leviticus 5:11) and the jealousy-offering (Numbers 5:15); for burning in lamps (Exodus 25:6; 27:20; Matthew 25:3); for medicinal purposes (Isaiah 1:6; Luke 10:34; James 5:14); and for anointing the dead (Matthew 26:12; Luke 23:56).

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 (Psalms 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 .)
