Repetition in The Epic of Gilgamesh

In The Epic of Gilgamesh, phrases, even whole stanzas are repeated. One of the many examples is:

"... there was a man came [by the watering hole.]

Mightiest in the land, strength [he possesses,]

[his strength] is as mighty [as a rock] from the sky (I 123-5)," which is repeated verbatim in I 150-3. The hunter speaks to two different people about Enkidu, his father and King Gilgamesh. In these descriptions, he uses the exact same phrases. Why is repetition so prevalent? It is most likely for emphasis of important facts. This could give insight into what that culture would have thought was important. For the first example given, it could be said that it is very important for the reader to note Enkidu's strength. This is the most straightforward way of emphasis, especially if this was to be read aloud to others. If you hear things repeated you will be more likely to remember the facts, especially when you are being read an epic, which is by definition, long. Another fact repeated multiple times is that Gilgamesh forces new brides to sleep with him before their husbands. This could be repeated multiple times to get the audience angry about this practice and for them to side with Enkidu who wants to put an end to it. The repetition is used for emphasis, but the emphasis means different things in different contexts.
