To see thy power... — The transposition of the clauses in the Authorised Version weakens the sense. Render, So (i.e., in this state of religious fervour) in the sanctuary have I had vision of thee in seeing thy might and glory. The psalmist means, that while he saw with his eyes the outward signs of Divine glory, he had a spiritual vision (the Hebrew word is that generally used of prophetic vision) of God.
