'Oil' in the Bible

For their mother has played the prostitute. She who conceived them has done shamefully; for she said, 'I will go after my lovers, who give me my bread and my water, my wool and my flax, my oil and my drink.'

For she did not know that I gave her the grain, the new wine, and the oil, and multiplied to her silver and gold, which they used for Baal.

and the earth will respond to the grain, and the new wine, and the oil; and they will respond to Jezreel.

Ephraim feeds on wind, and chases the east wind. He continually multiplies lies and desolation. They make a covenant with Assyria, and oil is carried into Egypt.
