"Even do, and spare not" motto of MacGregor. From The Adventures of Rob Roy.

Excerpt with phrase highlighted:
It chanced that on a day in summer, King
David I., of Scotland, was hunting with Malcolm
MacGregor, the eighth chief of Clan Alpine, on the
side of Cruachin, when a wild boar, of marvellous
strength, size, and ferocity, appeared in a rugged
defile. It at once assailed the monarch, whose
hunting-spear broke and left him at its mercy ; but
instead of rushing forward, the boar retired to whet
its tusks against the rocks, so Malcolm craved the
king's permission to attack it.


"E'en do," said the king; but spaire nocht !"
"Eadhon dean agus na caomhain!" shouted
MacGregor, translating the king's lowland Scottish
into Gaelic, as he tore up a young tree by the roots,
and kept the boar at bay until he could close with
it and bury his long dagger in its throat. At the
third stab he slew it.
