Genesis 2:18-20

18Now the Lord God said, “It is not good (beneficial) for the man to be alone; I will make him a helper [one who balances him—a counterpart who is] suitable and complementary for him.”

19So the Lord God formed out of the ground every animal of the field and every bird of the air, and brought them to Adam to see what he would call them; and whatever the man called a living creature, that was its name.

20And the man gave names to all the livestock, and to the birds of the air, and to every animal of the field; but for Adam there was not found a helper [that was] suitable (a companion) for him.
