'Feeds' in the Bible

A discerning mind seeks knowledge,but the mouth of fools feeds on foolishness.

W My love is mine and I am his;he feeds among the lilies.

I am my love’s and my love is mine;he feeds among the lilies.

He feeds on ashes.His deceived mind has led him astray,and he cannot deliver himself,or say, “Isn’t there a lie in my right hand?”
