Here's the old English poem! https://www.poetryfoundation.org/poems/47296/caedmons-hymn-5... Should be in the public domain by now eh?
Nu scilun herga hefenricæs uard
metudæs mehti and his modgithanc
uerc uuldurfadur sue he uundra gihuæs
eci dryctin or astelidæ.
he ærist scop ældu barnum
hefen to hrofæ halig sceppend
tha middingard moncynnæs uard
eci dryctin æfter tiadæ
firum foldu frea allmehtig
I couldn't make hide nor hair of it without the translation, but with the translation I see quite a few more words than just "and his" that have stayed around: hefen: heaven
uerc: work
uard: guard/ward
hrofæ: roof
æfter: after
middingard: Earth, to Marvel
allmehtig: almighty
