'Oil' in the Bible

Will the Lord be pleased with thousands of sheep or with ten thousand rivers of oil? am I to give my first child for my wrongdoing, the fruit of my body for the sin of my soul?

You will put in seed, but you will not get in the grain; you will be crushing olives, but your bodies will not be rubbed with the oil; and you will get in the grapes, but you will have no wine.
