The words for this comes from the first part of a sowing blessing from the Carmina Gadelica: a compendium of prayers, hymns, charms, incantations, blessings, literary-folkloric poems and songs, proverbs, lexical items, historical anecdotes, natural history observations, and miscellaneous lore gathered in the Gaelic-speaking regions of Scotland between 1860 and 1909.
The material was recorded, translated, and reworked by the exciseman and folklorist Alexander Carmichael (1832–1912).
I have created a melody for it so it can be sung for sowing:
I will go out to sow the seed
In name of him who gave it growth
I will place my front in the wind
And throw a gracious hand on high
Should a grain fall on a bare rock
It shall have no soil in which to grow
As much as falls into the earth
The dew will make to be full.
Friday, day auspicious,
The dew will come down to welcome
Every seed that lay in sleep
Since the coming of cold without mercy
Every seed will take root in the earth
As the king of the elements desired….
