At the beginning of adam (mankind), we, each one, were allowed to be a self-focused type of being. In that statement, the concept, self-focused, includes the immediate family members, almost exclusively . . . the nuclear family: husband, wife, sons and daughters. This limited focus had to be extended, outward, on all sides of the family.
The first level of extension occurs when we reach out to nephews, nieces, aunts, uncles, and grandchildren. This form of extension of the nuclear family was packaged in a most noble example: Noah. Noah, as by way of the Ark, extended his focus to all these others, in due time. This may not have been apparent, if one does not expand upon the potential that is in this action.
And Noah was six hundred years old when the flood of waters was upon the earth. And Noah went in, and his sons, and his wife, and his sons’ wives with him, into the ark, because of the waters of the flood. Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth, There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.
(Genesis 7:6-9)
To expand upon the understanding which is in that event, consider this Scripture.
