The naming finished. Targum Pseudo-Jonathan on (Genesis 2:20) closes the scene with a quiet loneliness: "Adam called the names of all cattle, and all fowl of the heavens, and all beasts of the field. But for Adam was not found as yet a helper before him."
The man has just performed an extraordinary act — he has read the soul of every living creature and matched it to a sound. He has done what only God had done before: call a thing into its name. And at the end of it, he is still alone. Every creature has a partner. He does not. The verse does not spell this out; the Targumist lets the silence do the work. Sometimes the most profound accomplishment only makes the absence of companionship louder.
