'Feeds' in the Bible

“A mother will forget him;The worm feeds sweetly till he is no longer remembered.And wickedness will be broken like a tree.

A boar from the forest eats it awayAnd whatever moves in the field feeds on it.

The mind of the intelligent seeks knowledge,But the mouth of fools feeds on folly.

He feeds on ashes; a deceived heart has turned him aside. And he cannot deliver himself, nor say, “Is there not a lie in my right hand?”

Ephraim feeds on wind,And pursues the east wind continually;He multiplies lies and violence.Moreover, he makes a covenant with Assyria,And oil is carried to Egypt.
