While we're on the subject of the Amalekites, the version I learned was:

GOLIATH OF GATH

Goliath of Gath
In hith helmet of brath
Wath theated one day
All on the green grath

When up wan thlim David
The thervant of Thaul
And thaid, "I will thlay you
"Although I am thmall."

He wan to the wiver
And chothe five thmooth thtoneth
To thling at Goliath
And break all hith boneth.

He dwew one, and thlang it -
It thoared through the thky
And thmote bold Goliath
Wight over the eye!

Goliath fell down
All on the gween thward
And up wan thlim David
And took up hith thword.

He picked up the thword
And hewed off hith head
And Ithrael thouted
"GOLIATH ITH DEAD!"

(a little unthertain about the conjunction between the thecond-latht and latht vertheth there.)
