Kings have Long Hands

Do not quarrel with a king, as his power and authority reach to the end of his dominions. The Latin proverb is, “An nescis longas regibus esse manus, ” and the German, “Mit grossen herren es ist nicht gut kirschen zu essen ” (“It is not good to eat cherries with great men, as they throw the stones in your eyes”).
