From the Carmina Gadelica (484–577)

The love and affection of the angels be to you,
The love and affection of the saints be to you,
The love and affection of heaven be to you,
To guard and cherish you.
May God shield you on every steep,
May Christ aid you on every path,
May Spirit fill you on every slope,
On hill and on plain.
May the king shield you in the valleys,
May Christ aid you on the mountains,
May Spirit bathe you on the slopes,
In hollow, on hill, on plain,
Mountain, valley and plain.

From Wikipedia: The Carmina Gadelica is a collection of prayers, hymns, charms, incantations, blessings, runes, and other literary-folkloric poems and songs collected and translated by amateur folklorist Alexander Carmichael (1832–1912) in the Gaelic-speaking regions of Scotland between 1855 and 1910.
