   • 10th century, The Wanderer:

     Til biþ sē þe his trēowe ġehealdeþ, · ne sċeal nǣfre his torn tō ryċene
     beorn of his brēostum ācȳþan, · nemþe hē ǣr þā bōte cunne,
     eorl mid elne ġefremman. · Wel bið þām þe him āre sēċeð,
     frōfre tō fæder on heofonum, · þǣr ūs eal sēo fæstnung stondeð.

     Good is that keeps his belief, should not ever unfold his wrath,
     fighter of his breasts, too quickly, unless before this help he would
     know how to help out a man with strength. It's good for him who seeks
     help from the Father in heavens, where this whole fastening stands for us.
