from the book, "Petrified Lightning"
And Zadok the priest took a horn of oil out of the tabernacle, and anointed Solomon.
1 Kings 1:39
The Bible is full of references to the installation of kings of ancient Israel by anointing them with holy oil.
In 1952 a copper scroll was discovered in the Holy Land. In the opinion of scholars, it contained a list of items taken from the temple of Jerusalem by pious Jews and hidden in a number of caves as the Roman army approached the city. As the Jews had anticipated, the Romans did destroy the temple of Jerusalem in a.d. 70.
One item listed on the copper scroll was excavated from a cave at Khirbat Qumran near the Dead Sea. It was a small earthen vessel filled with an oil wrapped in a nest of palm fibers. The excavating team first thought it was a flask filled with dirt, but outside the cave in bright daylight they noticed that a dark oily substance began to seep out. Most components of the oil have been identified by various chemical tests, but one elusive plant source remains a mystery.
It is believed that the Jews hid this bit of holy oil from the invaders because they knew the Romans valued it as a perfume!
