Olive Oil in Bible Times
The wide use of olive oil in Bible lands. Olive oil was considered to be one of the great sources of wealth in the days of King Solomon (cf. I Kings 5:11; II Chronicles 2:10). Solomon gave to Hiram each year in return for services rendered by his men, among other things, twenty thousand baths of oil, one bath being about seven and one-half gallons.
The prophets Ezekiel and Hosea make mention of the exporting of oil to other lands (Ezekiel 27:17; Hosea 12:1). Oil has been used for a great variety of purposes in the Orient. It largely took the place of butter in eating, and for cooking purposes it was used in place of animal fat.
Ezekiel mentions three important items of diet of which oil is one, and flour and honey are the other two (Ezekiel 16:13). And olive oil was used almost exclusively for light in lamps. The most famous example of this is "the ten virgins, which took their lamps, and went forth to meet the bridegroom" (Matthew 25:1). Also oil is used today in Bible lands in the manufacture of soap, and it is quite likely that it was so used in Bible days. And oil was often used for anointing the body.
Naomi told Ruth, "Wash thyself therefore, and anoint thee, and put thy raiment upon thee, and get thee down to the floor" (Ruth 3:3).
Then oil was many times used in various religious ceremonies. It formed a part of the meal offering (Leviticus 2:1). The prophet was anointed with oil when he took over his duties (I Kings 19:16). The priest was also anointed with oil when he took over his duties (Leviticus 8:12). And the king was anointed either by a prophet or by the priest (I Samuel 16:13; I Kings 1:34).
In New Testament times the sick were anointed for the healing of their bodies (Mark 6:13; James 5:14).
