Going and Coming

One of the first things I noticed about Trigony House Hotel was the lintel above the main doorway. Carved into the stone were the words:
The Lord bless thy going out and thy coming in.
A slightly more interesting and unusual 'welcome' sign than the ones you find at the entrance to most modern hotels!
Given the order of the 'prayer' (i.e. beginning with going out and ending with coming in) I wondered if it had more to do with wishing guests a good shooting expedition than simply welcoming them to the lodge for the first time but somehow, for me, it set the tone for our mini retreat.
Of course perhaps it is meant as a variation of the old Scottish way of saying goodbye "Haste ye back!" ...i.e. once you've gone, we hope you come back again soon.
Then again - maybe it's just because in the Psalm from which this is a virtual quotation (Psalm 121) going comes before coming.
I better stop rambling now because I don't know whether I'm coming or going!
