First and Last Interactions between Yahweh and Man in the J-Source

I was thinking today about the J (or Yahwist) source of the Pentateuch. Interestingly, Yahweh’s first interaction with Man in this work is his forming man out of the dust/dirt of the ground (Genesis 2:7) and then subsequently telling him that from the ground Man was created and to the ground Man returns (Genesis 3:19). If you turn all the way to the end of Deuteronomy 34, Yahweh’s last interaction with Man in the J-source is his burying Moses (Deuteronomy 34:5-6).
