I've been using Common Worship Daily Prayer for my private devotions for a few years now. (You can find a free daily feed here.) Each Psalm in Daily Prayer ends with a Collect.
Today's Collect for Psalm 76 really moved me, especially in this period of fear and violence that we seem to be living through:
Majestic and gracious God,
more awesome than the agents of war,
more powerful than the wrath of nations,
restrain the violence of the peoples
and draw the despised of the earth
into the joyful life of your kingdom,
where you live and reign for ever and ever.
