Time after time, critics have stated that portions of the Bible are false. But time after time, archaeologists chipping away with their hammers have uncovered evidence that supports the biblical account. But clay tablets from a period prior to Moses have now been discovered, describing many of the same rituals. There's no longer any reason to doubt that Moses wrote the Pentateuch, just as the Bible claims. Then cuneiform tablets were discovered with references to biblical names, like Abraham and his brothers, Nahor and Haran.
Archaeology also explains some unusual customs from biblical times.
Abraham's wife, Sarah, and Jacob's wife, Rachel, both offered servant girls to their husbands to bear children. Archaeology gives us the answer. It was a common practice in those times for a barren wife to provide her husband a surrogate. In many ways, the patriarchs were children of their age. A few centuries later, these practices were largely forgotten.
