You are more glorious and excellent than the mountains of prey.
Read Chapter 76
Augustine of Hippo
5. "Thou enlightening marvellously from the eternal mountains" (ver. 4). What are the eternal mountains? Those which He hath Himself made eternal; which are the great mountains, the preachers of truth. Thou dost enlighten, but from the eternal mountains: the great mountains are first to receive Thy light, and from Thy light which the mountains receive, the earth also is clothed. But those great mountains the Apostles have received, the Apostles have received as it were the first streaks of the rising light. ...Wherefore also, in another place, a Psalm saith what? "I have lifted up mine eyes unto the mountains, whence there shall come help to me." What then, in the mountains is thy hope, and from thence to thee shall there come help? Hast thou stayed at the mountains? Take heed what thou doest. There is something above the mountains: above the mountains is He at whom the mountains tremble. "I have lifted up," he saith, "mine eyes unto the mountains, whence there shall come help to me." ...

"Thou art a light magnificently from (Haydock) or more than, (Berthier) the mountains of the captivity. "(St. Jerome)
Or, "of prey. "(Protestants)
"Thou art more terrible. Than the richest mountains. "(Theodoret)
Yet this comparison hardly suits in this place, (Calmet) and Houbigant prefers the Vulgate and Septuagint, who may have read terem, "before "or saraph, "of the seraph "(alluding to God's seat upon the ark) instead of tareph, "prey. "(Berthier)
God grants victory to his people, and enlightens them with the true faith. (Worthington)
