''Wounded I hung on a wind-swept gallows
For nine long nights,
Pierced by a spear,
pledged to Odin,
Offered, myself to myself
The wisest know not from whence spring
The roots of that ancient rood.
[...]
To learn to sing them, Loddfafnir,
Will take you a long time,
Though helpful they are if you understand them,
Useful if you use them,
Needful if you need them.
[...]
Hail to the speaker,
Hail to the knower,
Joy to him who has understood,
Delight to those who have listened.''
-The Hàvamàl
