Inclusio
The ancient Hebrews authors loved inclusio. Inclusio is type of bracketing, or enveloping by placing similar material at the beginning and the end of a section.
Ancient Babylonian tablets which predate Abraham used bracketing as a way to indicate when an account was finished, even though there may be more writing on the tablet.
We note the inclusio as ABA where A is the pattern which is at the beginning and end of the section; B is the content enveloped by the inclusio.
