'Oil' in the Bible

From the sole of the foot even unto the head there is no soundness in him; wounds, and weals, and open sores: they have not been dressed, nor bound up, nor mollified with oil.

And Hezekiah was glad of them, and shewed them the house of his precious things, the silver and the gold, and the spices and the fine oil, and all the house of his armour, and all that was found amongst his treasures: there was nothing in his house, nor in all his dominion, that Hezekiah did not shew them.

to appoint unto them that mourn in Zion, that beauty should be given unto them instead of ashes, the oil of joy instead of mourning, the garment of praise instead of the spirit of heaviness: that they might be called terebinths of righteousness, the planting of Jehovah, that he may be glorified.
