There is yet another picture of the Father, Son, and Spirit in Genesis 26:25:

Father: Isaac built an altar and called on YHWH.
Son: Isaac pitched a tent/tabernacle/manger at the spot.
Spirit: Unnamed servants dug a well that later released living water.

As I've stated a number of times, I don't think the idea of the Trinity is wrong. It's just incomplete. It's one attempt to describe the indescribable. There is more mystery in God than in all the philosophies in mankind and we can never hope to fully understand him. Tom Bradford's comments in this article come pretty close to what I believe: http://torahclass.com/old-test....ament-studies-tc/39-
