Who is Us?

My question pertains to Genesis 3:22. Specifically, in whom is God referring to when he states Adam is one of us, who is us? Is this the triune God?

Certainly, this and other verses indicate the triune God. At the least, they show God to be a plurality while at the same time only one. Consider the following verses:

Genesis 1:26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Genesis 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Genesis 11:7 Go to, let us go down, and there confound their language, that they may not understand one another's speech.
Isaiah 6:8 Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.

This last verse (Isaiah 6:8) has the Lord identified as "I" and "us" at the same time. This is a plurality in a unity. He is the three-in-one God.

Whoso keepeth the law is a wise son: but he that is a companion of riotous men shameth his father.
