from many a tribe, the mead-bench tore,
awing the earls. Since erse he lay
friendless, a foundling, fate repaid him:
for he waxed under welkin, in wealth he trove,
till before him the folk, both far and near,
who house by the whale-path, heard his mandate,
gabe him gits: a good king he!
To him an heir was afterward born,
a son in his halls, whom heaven sent
to favor the fol, feeling their woe
that erst they had lacked an earl for leader
so long a while; the Lord endowed him,
the Wielder of Wonder, with world's renown.
