The Hebrew word isha, "woman," is the name Adam gave Eve. The Hebrew word for man is ish, and Adam named her isha because she was taken out of man. He recognized her as "bone of my bones and flesh of my flesh." The names acknowledge both likeness and slight difference. Among all the animals Adam had named, none was like him or comparable to him, but God made the woman specifically for him, so she became a fitting companion. The gender difference is slight, and together as one flesh a man and woman can produce their own kind and so continue mankind. English preserves the same idea in "woman," meaning man with a womb. The naming illustrates the principle that the namer stands in a position of authority over what is named, and that a name identifies its bearer. This first use of shem, the Hebrew word for name, in the same passage also hints at continuance. A name can denote not only a person but also the progeny and inheritance carried on through the generations, as when Boaz speaks of perpetuating the name of the dead.
