Iam Lucis Orto Sidere (Prime Morning Hymn)

Now doth the sun ascend the sky, And wake creation with its ray; Keep us from sin, O Lord most high! Through all the actions of the day. Curb Thou for us the unruly tongue; Teach us the way of peace to prize; And close our eyes against the throng Of earth's absorbing vanities. Oh, may our hearts be pure within! No cherished madness vex the soul! May abstinence the flesh restrain, And its rebellious pride control. So when the evening stars appear, And in their train the darkness bring; May we, O Lord, with conscience clear, Our evening hymn of glory sing. Amen.
