The Hávamál Norse Mythology Book – Verse 113 - 114
Beware of sleep | on a witch's bosom,
Nor let her limbs ensnare thee.
Such is her might | that thou hast no mind
For the council or meeting of men;
Meat thou hatest, | joy thou hast not,
And sadly to slumber thou farest.
-Hávamál v113-114, Bellows translation
