'Oil' in the Bible

For their mother has been untrue; she who gave them birth has done things of shame, for she said, I will go after my lovers, who give me my bread and my water, my wool and my linen, my oil and my wine.

For she had no knowledge that it was I who gave her the grain and the wine and the oil, increasing her silver and gold which they gave to the Baal.

And the earth will give its answer to the grain and the wine and the oil, and they will give an answer to Jezreel;

Ephraim's food is the wind, and he goes after the east wind: deceit and destruction are increasing day by day; they make an agreement with Assyria, and take oil into Egypt.
