Generation and expiration, birth and death, musical patterns

Not only birth and children in Genesis of course, but also expiration and death. Abraham's death illustrates common patterns in the music of Torah. Here is the page where Abraham dies.

Notice the differing ways in which the diminished triad is used to approach a cadence either on the tonic or the subdominant.

We have six examples on the page:
1. D-E-F-G#-A
2. D-F-G#-F-E
3. D-F-G#-B-A
and he was gathered to his people - and then his sons buried him - in the purchased burial ground...
4. same as 3
5. same as 2
6. a new variation.

Can you see a circular pattern emerging? I wonder to what extent this is frequent in the music...
