Genesis 2:20

And Adam gave names. — Throughout this chapter Adam is but once mentioned as a proper name; and the regular phrase in the Hebrew is the adam, that is, the man, except in the last clause of this verse. In Genesis 2:23 there is a different word for man, namely, ish. We must not confine this giving of names to the domestic animals, nor are we to suppose a long procession of beasts and birds passing before the man, and receiving each its title. Rather, it sets him before us as a keen observer of nature; and as he pursues his occupations in the garden, new animals and birds from time to time come under his notice, and these he studies, and observes their ways and habits, and so at length gives them appellations. Most of these titles would be imitations of their cries, or would be taken from some marked feature in their form or plumage, or mode of locomotion. Adam is thus found possessed of powers of observation and reflection upon the natural objects round him; though we may justly doubt his being capable of the metaphysical discourses put into his mouth by Milton in the Paradise Lost.

But for Adam. — In this one place there is no article, and our version may be right in regarding it as a proper name. Among the animals Adam found many ready to be his friends and domestic servants; and his habits of observation had probably this practical end, of taming such as might be useful. Hence the omission of all notice of reptiles and fish. But while thus he could tame many, and make them share his dwelling, he found among them no counterpart of himself, capable of answering his thoughts and of holding with him rational discourse.
