Religious scholars say that God suspended the laws of incest in the early days of man in order to ensure that man spread on the earth. In the words of the commentators of the Douay Rheims Bible: “God [dispensed] with such marriages in the beginning of the world, as mankind could not otherwise be propagated.” Despite that, these tales are not all simply matters of procreation - particularly item 1. So, here is a list of 6 of the more questionable relationships in the Bible.

And Cain went out from the face of the Lord, and dwelt as a fugitive on the earth, at the east side of Eden. And Cain knew his wife, and she conceived, and brought forth Henoch: and he built a city, and called the name thereof by the name of his son Henoch. [Genesis 4:16-17]
Cain was the first born son of Adam and Eve, and Abel was the second. In Genesis 4 we read how Cain kills his brother and is sent east of Eden where he marries a woman and “lays” with her. Because Adam and Eve were the first humans - from whom all people come - Cain’s wife was his sister - and, consequently, all of the early Biblical relationships were incestuous (with the exception of Adam and Eve). Cain, incidentally, was the guy that caused so much trouble for the Mormon’s who believed that the cursed “Mark of Cain” meant black skin, leading them to forbid blacks from entering the Mormon priesthood (God “revealed” that they were allowed to let black skinned people in to the priesthood in 1978). You can read more about that blunder here. In the image above we see Cain killing his brother Abel.
