Albert Barnes Commentary Genesis 2:18

"And Jehovah God said, It is not good that the man should be alone; I will make him a help meet for him." — Genesis 2:18 (ASV)

Here man’s intellectual faculties proceed from the passive and receptive to the active and communicative stage. This advance is made in the review and designation of the various species of animals that frequent the land and skies.

A new and final need of man is stated in (Genesis 2:18). The Creator himself, in whose image he was made, had revealed himself to him in language. This, among many other effects, awakened the social affection. This affection was the index of social capacity. The first step towards communication between kindred spirits was accomplished when Adam heard and understood spoken language. Beyond all this, God knew what was in the man whom he had formed.

And he expresses this in the words, It is not good for the man to be alone. He is formed to be social, to hold converse not only with his superior, but also with his equal. As yet, he is but a unit, an individual. He needs a mate, with whom he may take sweet counsel. And the benevolent Creator resolves to supply this need. I will make him a helpmeet for him—one who may not only reciprocate his feelings, but take an intelligent and appropriate part in his active pursuits.
