Folks, I could some help with a translation of the first line of Verse 73 of the Havamal.

"Tveir ro eins herjar" - any insight?


here is the whole verse in case that context is helpful.:

Tveir ro eins herjar,
tunga er höfuðs bani;
er mér í heðin hvern
handar væni.

Thanks in advance for any assistance!

Hugh
