'Shepherd' in the Bible

As a shepherd His flock He feedeth, With His arm He gathereth lambs, And in His bosom He carrieth them: Suckling ones He leadeth.

Who is saying of Cyrus, My shepherd, And all my delight He doth perfect, So as to say of Jerusalem, Thou art built, And of the temple, Thou art founded.

And He remembereth the days of old, Moses -- his people. Where is He who is bringing them up from the sea, The shepherd of his flock? Where is He who is putting in its midst His Holy Spirit?
