Genesis 3:15

The rabbi's (etc.) do have a response to it, but I agree - it doesn't wash.

I take it as the Trinity.

Of course the Jews don't believe the Book of John, but as you pointed out previously, reading John 1:1-3 lets us recognize what is meant by 'us' in Genesis 1:26.

You can also see us in other places.

Genesis 3:22, Genesis 11:7, Isaiah 6:8.
