". . . Ariel means something like 'altar hearth' and may designate the altar of burnt offering as a symbolic reference to Jerusalem. . . . [Thus] Jerusalem . . . will become a place for sacrifice or slaughter (Isa 29:2). Ariel . . . may also be related to the etymology of ʾari ʾel (lion of God) since Judah is called a lion's whelp in Gen 49:9. Others detect an allusion to . . . har ʾel . . . that is, Jerusalem as the 'mountain of God.' . . ."
Ralph W. Klein, "Ariel," New interpreter's dictionary of the Bible (Nashville, TN: Abingdon Press, 2006), vol. 1, p. 259.
