My beloved is mine, and I am his: he feedeth among the lilies.

I am my beloved's, and my beloved is mine: he feedeth among the lilies.

He feedeth on ashes: a deceived heart hath turned him aside, that he cannot deliver his soul, nor say, Is there not a lie in my right hand?

Ephraim feedeth on wind, and followeth after the east wind: he daily increaseth lies and desolation; and they do make a covenant with the Assyrians, and oil is carried into Egypt.
