'Feedeth' in the Bible

The heart of him that hath understanding seeketh knowledge; But the mouth of fools feedeth on folly.

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

I am my beloved's, and my beloved is mine; He feedeth his flock among the lilies,

He feedeth on ashes; a deceived heart hath turned him aside; and 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 continually multiplieth lies and desolation; and they make a covenant with Assyria, and oil is carried into Egypt.
