The Twentieth Sunday after Trinity
O ALMIGHTY and most merciful God, of thy bountiful goodness keep us, we beseech thee, from all things that may hurt us; that we, being ready both in body and soul, may cheerfully accomplish those things which thou commandest; through Jesus Christ our Lord. Amen.

This Sunday Psalm 116 is appointed. In my prayer book it begins as "My delight is in the Lord." I am reminded of David's time in the wilderness, avoiding Saul's wrath (this may have been the time he wrote this psalm.) "Turn again then unto thy rest, O my soul; for the Lord hath done good to thee" When Saul encamped against David, the Lord put a deep sleep on Saul and his men, so that David was able to walk into the camp and take Saul spear, but render him no harm. I think too of our own centurions in harms way this very day. This psalm must have special meaning to them. The snares (IEDs) of death surround them. Their enemy plot against them. May God in his mercy comfort, help, and preserve them, and may their souls find peace and rest in his presence.
I commend Augustine's exposition of the psalm at the link above.
