Eiðr ok Blóð, “Oath and Blood,” is a song about the most sacred bond in the Viking world: the sworn oath. It is a driving, defiant anthem of brotherhood and loyalty, of warriors who bind themselves to one another by oath and blood and stand shield to shield to the very end. In a culture where a person’s word was their honor and their life, this song gives voice to the unbreakable vow, and to the doom that falls on any who break it.

This is the sound of the oath-bound war-band: fierce, loyal, and true to death.

The Sacred Oath

The heart of this song is the oath, and its opening lines state its power directly: “The oath is a sword, blood is the mark, words are bound, never undone.” In the Norse world, an oath was among the most sacred and serious things a person could give. It was not a casual promise but a binding of the self, as real and as sharp as a sword.

“Carved in stone, oath and self as one.” This captures the Norse understanding perfectly. To swear an oath was to make it part of who you were; the oath and the self became one. A person was only as good as their word, and to keep faith was the foundation of all honor. The song treats the oath with the gravity it held for the Vikings: an unbreakable bond, carved in stone, standing firm in the darkness.

Blood and Brotherhood

The song ties the oath to blood and to the bond between warriors who fight together. “With brothers we stand, shield to shield, hearts beat like hammer blows.” This is the image of the Viking war-band at its core: not a collection of individuals, but a brotherhood bound by shared oaths and standing together in the shield wall.

The shield wall was the heart of Viking battle tactics, and it depended entirely on trust. Each warrior protected the one beside him; to hold the line was to hold faith with your brothers. The song makes this bond sacred: “Oath and blood! Life and bond!” The oath sworn in blood joins the warriors into one body, and their loyalty to one another becomes as binding as any vow to the gods. “Many wounds, yet the spirit is whole.” Bound together, they endure everything, because the bond itself does not break.

The Doom of the Oath-Breaker

The song does not only celebrate the oath; it names the price of breaking it. “He who betrays shall die swiftly.” In the Norse world, there was no crime more shameful than oath-breaking. To break a sworn oath was to destroy one’s honor utterly, and the oath-breaker was among the most despised of all figures.

This was no small matter. The Norse sources reserve some of their darkest fates for oath-breakers; in the vision of the afterlife, one of the worst places of punishment, Náströnd, the Shore of Corpses, was reserved for oath-breakers and betrayers. The song carries this weight: “Judgment comes late, but never divided.” The judgment on the faithless may not come at once, but it comes, certain and undivided. To swear “oath and blood” was to accept both sides of the bargain: the strength of the bond, and the doom that follows its betrayal.

Men to the End

The song builds to a final declaration of total commitment: “Oath and blood! We still stand! Men to the end!” This is the ultimate expression of the oath: loyalty not just for a day or a battle, but to the very end, whatever comes.

“Ancient is the word, no escape.” The oath is old, older than any single warrior, part of the deep code that bound Norse society together. And there is no escape from it, not because one is trapped, but because a true warrior would never wish to escape it. To stand by your oath to the end, shield to shield with your brothers, facing whatever fate brings without flinching, was the highest honor a Norse warrior could claim. The song ends on that unbroken vow: bound by oath and blood, standing firm, men to the end.

Eiðr ok Blóð Lyrics (Old Norse and English)

The lyrics are given first in the original Old Norse, then in English translation.

Old Norse:

Eiðr er sverðr, blóð er spor,
orð eru bundin, rofin ei for.

Í myrkri stendr eiðr minn,
rist í stein, eiðr ok sinn.
Blóð fellr lágt á kalda mold,
sá er svíkr, mun deyja skjǫlt.

Eiðr ok blóð! Bundit fast!
Eiðr ok blóð! Aldri kast!
Eiðr ok blóð! Stendr vér við!
Eiðr ok blóð! Líf ok lið!

Við bræður stendr, skjǫldr við skjǫldr,
hjarta slær sem hamars gjǫld.
Sár eru mörg, en hugr er heill,
dómr kemr seint, en aldri deil.

Eiðr ok blóð! Bundit fast!
Eiðr ok blóð! Aldri kast!
Eiðr ok blóð! Stendr vér við!
Eiðr ok blóð! Líf ok lið!

Eiðr ok blóð! Fornt er orð!
Eiðr ok blóð! Engi flótti!
Eiðr ok blóð! Við stöndum enn!
Eiðr ok blóð! Til enda menn!

Eiðr… ok blóð…

English translation:

The oath is a sword, blood is the mark,
Words are bound, never undone.

In darkness my oath stands,
Carved in stone, oath and self as one.
Blood falls low upon cold earth,
He who betrays shall die swiftly.

Oath and blood! Bound tight!
Oath and blood! Never cast aside!
Oath and blood! We stand by it!
Oath and blood! Life and bond!

With brothers we stand, shield to shield,
Hearts beat like hammer blows.
Many wounds, yet the spirit is whole,
Judgment comes late, but never divided.

Oath and blood! Bound tight!
Oath and blood! Never cast aside!
Oath and blood! We stand by it!
Oath and blood! Life and bond!

Oath and blood! Ancient is the word!
Oath and blood! No escape!
Oath and blood! We still stand!
Oath and blood! Men to the end!

Eiðr… ok blóð…
