Due to manuscript differences, translations of the stanza vary:  Regarding this stanza, scholar Andy Orchard comments that the name "Gjallarhorn" may here mean "horn of the river Gjöll" as "Gjöll is the name of one of the rivers of the Underworld, whence much wisdom is held to derive", but notes that in the poem "Grímnismál" Heimdallr is said to drink fine mead in his heavenly home Himinbjörg. Earlier in the same poem, the völva mentions a scenario involving the hearing or horn (depending on translation of the Old Norse noun "hljóð"—translations bolded below for the purpose of illustration) of the god Heimdallr:  Scholar Paul Schach comments that the stanzas in this section of " Völuspá" are "all very mysterious and obscure, as it was perhaps meant to be". Schach details that ""Heimdallar hljóð" has aroused much speculation. Snorri [in the "Prose Edda"] seems to have confused this word with "gjallarhorn", but there is otherwise no attestation of the use of "hljóð" in the sense of 'horn' in Icelandic. Various scholars have read this as "hearing" rather than "horn". Scholar Carolyne Larrington comments that if "hearing" rather than "horn" is understood to appear in this stanza, the stanza indicates that Heimdallr, like Odin, has left a body part in the well; his ear. Larrington says that "Odin exchanged one of his eyes for wisdom from Mimir, guardian of the well, while Heimdall seems to have forfeited his ear." In the poem "Grímnismál", Odin (disguised as "Grímnir"), tortured, starved and thirsty, tells the young Agnar of a number of mythological locations. The eighth location he mentions is Himinbjörg, where he says that Heimdallr drinks fine mead:  Regarding the above stanza, Henry Adams Bellows comments that "in this stanza the two functions of Heimdall—as father of humanity [ . . . ] and as warder of the gods—seem both to be mentioned, but the second line in the manuscripts is apparently in bad shape, and in the editions it is more or less conjecture".
