Hello!
Your questions is incomplete. The complete poem is:
An Arab Shepherd Is Searching For His Goat On Mount Zion
An Arab shepherd is searching for his goat on Mount Zion / and on the opposite hill I am searching for my little boy. / An Arab shepherd and a Jewish father / both in their temporary failure. / Our two voices met above / the Sultan’s Pool in the valley between us. / Neither of us wants the boy or the goat / to get caught in the wheels / of the “Chad Gadya” machine. / Afterward we found them among the bushes, / and our voices came back inside us / laughing and crying. / Searching for a goat or for a child has always been / the beginning of a new religion in these mountains.

The whole text has cultural references. Mount Zion, by its use and historical significance, the "sultan's swimming pool", being a specific reference of an Arab culture and the Chad Gaya, for being a musical style. The Arab shepherd, however, enters more into the perspective of common sense, and could be seen, from an alternative perspective, as an emptiness of cultural meaning.

Rhyme and rhythm are two techniques that are being used. (Edit) also repetition.
<span>The use of the phrasing "a date which will live in infamy" is an example of an application of an aphorism in speechwriting. An aphorism is a short saying which encapsulates a meaning or idea so fully that it can continue to live on in its own right beyond the context of its initial application. FDR's statement falls squarely into this category, having been used in continual application for many decades since its initial use.</span>
