Genesis 5:1-2

"This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him; male and female created he them, and blessed them, and called their name Adam, in the day when they were created."

"The generations of Adam ..." Here is the same Hebrew word, [~toledowth], used nine other times in Genesis. Note the recapitulation regarding God having created man "in the image of God," etc., thus exhibiting the same pattern observable in the account of the description of the [~toledowth] of the heavens and the earth (Genesis 2:4). This is therefore not a clumsy effort to recount God's naming of his human creation at a later date, but a reference to what had already been done. Some of this information is, of course, supplementary. We learn here that Adam was the family name as well as the personal name of Adam.
