1: This is the book of the generation of Adam. In the day that God
created man, he made him to the likeness of God.
1: This [is] the genealogy of men in the day in which God made Adam; in the image of God he made him:
This is the book of the generations of Adam.
This statement may end the preceding section and represent the personal account of Adam. Adam's account would cover all the activities in the garden of Eden and afterwards till the close of Adam's life. That which follows would then be the account written by Noah and describe that time from Adam until Noah. Very little information is provided about the times between Adam and Noah.
Gill takes this to be the beginning of that which follows and writes, "An account of persons born of him, or who descended from him by generation in the line of Seth, down to Noah, consisting of ten generations; for a genealogy of all his descendants is not here given, not of those in the line of Cain, nor of the collateral branches in the line of Seth, only of those that descended one from another in a direct line to Noah:"
Clarke writes, "[that] which we generally translate book, signifies a register, an account, any kind of writing, even a letter, such as the bill of divorce. Here It means the account or register of the generations of Adam or his descendants to the five hundredth year of the life of Noah."
In the day that God created man, in the likeness of God made he him;
Gill writes, "this is repeated from Gen 1:27 to put in mind that man is a creature of God; that God made him, and not he himself; that the first man was not begotten or produced in like manner as his sons are, but was immediately created; that his creation was in time, when there were days, and it was not on the first of these, but on the sixth; and that he was made in the likeness of God, which chiefly lay in knowledge, righteousness, and holiness, and in dominion over the creatures."
Clarke writes, "This account is again introduced to keep man in remembrance of the heights of glory whence he bad fallen; and to prove to him that the miseries and death consequent on his present state were produced by his transgression, and did not flow from his original state. For, as he was created in the image of God, he was created free from natural and moral evil. As the deaths of the patriarchs are now to be mentioned, it was necessary to introduce them by this observation, in order to justify the ways of God to man."
