It's two sentences. One I've already figured out, I think:
"Tanin'iver Liftoach Nia" (תנין עִוֵּר לפתוח עין I guess) means "blind dragon, open your eyes"?
"Tohu Tehom Theli Than Leviathan Tanin'iver Taninsam" (google translate transliterated it to
תוהו תהום תהלי טחן לויאטהן תננאבר תננסאם but it seems not quite right)
I think I understand "tanin'iver", "tohu", "tehom" and, obviously, "leviathan" but I can't understand what the complete sentence means.
The band used quite a couple of different languages in their lyrics (normally only some words or lines per song) - so if someone wants to check whether s/he recognized which language the phrases are written in, here:
(I'll only link those that I haven't already found out myself)
Some may also be pseudo-languages or mixes of idioms, without any real meaning.
