'Beholders' in the Bible

Thy beholders look to thee, to thee they attend, Is this the man causing the earth to tremble, Shaking kingdoms?

And not dazzled are the eyes of beholders, And the ears of hearers do attend.

And known among nations hath been their seed, And their offspring in the midst of the peoples, All their beholders acknowledge them, For they are a seed Jehovah hath blessed.
