Here is an important post in the Celestial forum where I have an imaginary conversation with Jeff Lindsay wherein I show how Joseph Smith dated Old Testament events printed in the Doctrine and Covenants and given to the entire Church in the Lectures of Faith. I recommend readers read or review it for the sake of this thread.
And in this same vein, I would like to quote additional material from the Lecture which were faith sustaining beliefs held by all Latter-day Saints in Joseph Smith’s time and for over eighty years after.
LECTURE SECOND. Of Faith. SECTION II. wrote:45 Having traced the chronology of the world from Adam to Noah, we will now trace it from Noah to Abraham. Noah was 502 years old when Shem was born: 98 years afterward the flood came, being the 600th year of Noah’s age. And Moses informs us that Noah lived after the flood, 350 years: making him 950 years old when he died. Gen. 9:28, 29.
46 Shem was 100 years old when Arphaxed was born. Gen. 11:10, Arphaxed was 35 when Salah was born 11:12. Salah was 30 when Eber was born. 11:14. Eber was 34 when Peleg was born: in whose days the earth was divided. 11:16. Peleg was 30 when Reu was born. 11:18. Reu was 32 when Serug was born. 11:20. Serug was 30 when Nahor was born. 11:22. Nahor was 29 when Terah was born. 11:24. Terah was 70 when Haran and Abraham were born. 11:26.
47 There is some difficulty in the account given by Moses, of Abraham’s birth. Some have supposed, that Abraham was not born until Terah was 130 years old. This conclusion is drawn from a variety of scriptures, which are not to our purpose at present to quote. Neither is it a matter of any consequence to us, whether Abraham was born when Terah was 70 years old, or 130. But in order that there may no doubt exist upon any mind, in relation to the object lying immediately before us, in presenting the present chronology, we will date the birth of Abraham at the latest period: that is, when Terah was 130 years old. It appears from this account, that from the flood to the birth of Abraham was 352 years.
48 Moses informs us that Shem lived, after he begat Arphaxad, 500. Gen. 11:11. This added to 100 years, which was his age when Arphaxed was born, makes him 600 years old when he died. Arphaxed lived, after he begat Salah, 403 years. 11:13. This added to 35 years, which was his age when Salah was born, makes him 438 years old when he died. Salah lived, after he begat Eber, 403 years. 11:15.— This added to 30 years, which was his age when Eber was born, makes him 433 years old when he died.— Eber lived, after he begat Peleg, 430 years. 11:17. This added to 34 years, which was his age when Peleg was born, makes him 464 years old. Peleg lived, after he begat Reu, 209 years. 11:19. This added to 30 years, which was his age when Reu was born, makes him 239 years old when he died. Reu lived, after he begat Serug, 207 years. Gen. 11:21. This added to 32 years, which was his age when Serug was born, makes him 239 years old when he died. Serug lived, after he begat Nahor, 200 years. Gen. 11:23. This added to 30 years, which was his age when Nahor was born, makes him 230 years old when he died. Nahor lived, after he begat Terah, 119 years. Gen. 11:25. This added to 29 years, which was his age when Terah was born, makes him 148 years when he died. Terah was 130 years old when Abraham was born, and is supposed to have lived 75 years after his birth: making him 205 years old when he died.
49 Agreeably to this last account, Peleg died in the 1996th year of the world, Nahor in the 1997th, and Noah in the 2006th. So that Peleg, in whose days the earth was divided, and Nahor, the grand-father of Abraham, both died before Noah: the former being 239 years old, and the latter 148. And who cannot but see, that they must have had a long and intimate acquaintance with Noah?
50 Reu died in the 2026th year of the world, Serug in the 2049th, Terah in the 2083rd, Arphaxed in the 2096th, Selah in the 2126th, Shem in the 2158th, Abraham in the 2183rd, and Eber in the 2187th: which was 4 years after Abraham’s death. And Eber was the fourth from Noah.
51 Nahor, Abraham’s brother, was 58 years old when Noah died, Terah 128, Serug 187, Reu 219, Eber 283, Salah 313, Arphaxed 344, and Shem 448.
52 It appears from this account, that Nahor, brother of Abraham, Terah, Nahor, Serug, Reu, Peleg, Eber, Salah, Arphaxed, Shem, and Noah, all lived on the earth at the same time. And that Abraham was 18 years old when Reu died, 41 when Serug and his brother Nahor died, 75 when Terah died, 88 when Arphaxed died, 118 when Salah died, 150 when Shem died, and that Eber lived 4 years after Abraham’s death. And that Shem, Arphaxed, Salah, Eber, Reu, Serug, Terah, and Nahor, the brother of Abraham, and Abraham, lived at the same time.— And that Nahor, brother of Abraham, Terah, Serug, Reu, Eber, Salah, Arphaxed, and Shem, were all acquainted with both Noah and Abraham.
53 We have now traced the chronology of the world, agreeably to the account given in our present Bible, from Adam to Abraham, and have clearly determined, beyond the power of controversy, that there was no difficulty in preserving the knowledge of God in the world, from the creation of Adam, and the manifestation made to his immediate descendants, as set forth in the former part of this lecture, so that the students, in this class need not have any dubiety resting on their minds, on this subject; for they can easily see, that it is impossible for it to be otherwise; but that the knowledge of the existence of a God, must have continued from father to son, as a matter of tradition, at least. For we cannot suppose, that a knowledge of this important fact, could have existed in the mind of any of the before mentioned individuals, without their having made it known to their posterity.
54 We have now shown how it was that the first thought ever existed in the mind of any individual, that there was such a being as a God, who had created and did uphold all things: that it was by reason of the manifestation which he first made to our father Adam, when he stood in his presence, and conversed with him face to face, at the time of his creation.
55 Let us here observe, that after any portion of the human family are made acquainted with the important fact that there is a God who has created and does uphold all things, the extent of their knowledge, respecting his character and glory, will depend upon their diligence and faithfulness in seeking after him, until like Enoch the brother of Jared, and Moses, they shall obtain faith in God, and power with him to behold him face to face.
56 We have now clearly set forth how it is, and how it was, that God became an object of faith for rational beings; and also, upon what foundation the testimony was based, which excited the enquiry and diligent search of the ancient saints, to seek after and obtain a knowledge of the glory of God: and we have seen that it was human testimony, and human testimony only, that excited this enquiry, in the first instance in their minds—it was the credence they gave to the testimony of their fathers—this testimony having aroused their minds to enquire after the knowledge of God, the enquiry frequently terminated, indeed, always terminated, when rightly persued, in the most glorious discoveries, and eternal certainty.
