'Shepherd' in the Bible

And they are scattered from want of a shepherd, And are for food to every beast of the field, Yea, they are scattered.

I live -- an affirmation of the Lord Jehovah, If not, because of My flock being for a prey, Yea, My flock is for food to every beast of the field, Because there is no shepherd, And My shepherds have not sought My flock, And the shepherds do feed themselves, And My flock they have not fed.

And have raised up over them one shepherd, And he hath fed them -- my servant David, He doth feed them, and he is their shepherd,

And My servant David is king over them, And one shepherd have they all, And in My judgments they go, And My statutes they keep, and have done them.
