'Partridge' in the Bible

And now, let not my blood fall to the earth over-against the face of Jehovah, for the king of Israel hath come out to seek one flea, as one pursueth the partridge in mountains.'

A partridge hatching, and not bringing forth, Is one making wealth, and not by right, In the midst of his days he doth forsake it, And in his latter end -- he is a fool.
