The Prose Edda 1.41

Then said Gangleri: "A very mighty multitude of men is in Valhall, so that, by my faith, Odin is a very great chieftain, since he commands so large an army. Now what is the sport of the champions, when they are not fighting?" Hárr replied: "Every day, as soon as they are clothed, they straightway put on their armor and go out into the court and fight, and fell each other. That is their sport; and when the time draws near to undern-meal, they ride home to Valhall and sit down to drink, even as is said here:

All the Einherjar in Odin's court Deal out blows every day; The slain they choose and ride from the strife,— Sit later in love together.

But what thou hast said is true: Odin is of great might. Many examples are found in proof of this, as is here said in the words of the Æsir themselves:

Ash Yggdrasill's trunk of trees is foremost, And Skídbladnir of ships; Odin of Æsir, of all steeds Sleipnir, Bifröst of bridges, and Bragi of skalds; Hábrók of hawks, and of hounds Garmr."
