What line in Beowulf best foreshadows the outcome of the battle between Beowulf and Grendel?

"In his far-off home Beowulf, Higlac's Follower and the strongest of the Geats-greater and stronger than anyone anywhere in this world-heard how Grendel filled nights with Horror and quickly commanded a boat fitted out, proclaiming that he'd go to that famous king. Would sail across the sea to Hrothgar now when help was needed."
