The Scout Benediction
"May the Great Scoutmaster of all Scouts be with you(us) until we meet again."
The actual wording is taken from a training course offered in Texas in the middle 30s, from what I understand. There are some variations I've used and found over the years:
"May the Creator of all things Great and Small, watch over you and bring you back within this circle again soon."
"May the great Master of all Scouts be with you until we next clasp hands."
"May the Trinity of Life grant you safe passage to your homes, gives you ways to use the Scouting ideals, and return you safely to all of us again next week."
One of my favorites:
"May the Spirit which brought us together this week keeps us mindful of our Obligations during the week and remind us of our need to learn, share and return here again."
"May the Scoutmaster of all those who will listen to Him prepare you for leaving this room; may He continue to remind you to help other people and to do your best during this week; may He return you safely to your families and friends; and may you humble yourself in continuing to listen and follow His guidance and direction."
There's a couple others out there, I'm sure. All of them are ended with the words:
"Good night Scouts!" or "Good night, Scouters!"
