ABC:Genesis 16

From BibleStrength

Verse 15

The ReasonProject lists the following as a Bible contradiction with the headline "How many sons did Abraham have?"[1]

It is very odd first of all that Genesis 4:22 is included here as a contradiction, I can only assume the chart designer made a typo here as the passage is entirely unrelated. They must have intended another passage but I can't figure out which one.

Regardless, the usage of the word "son" each time was in reference to an heir. This is apparent throughout both the Old and New Testaments. Sarah, because she was originally infertile, made the somewhat ill-advised decision to ask her maid to bear Abraham's children, which she quickly recognized had been a mistake afterward. (Genesis 16:1-6) Abraham had multiple children, but only one he considered "son" in the sense of being an heir. The other sons of Abraham were not considered sons but servants. (Galatians 4:30, Genesis 21:10) Thus, Abraham sent the illegitimate children away with gifts but the overall inheritance went to Isaac alone. (Genesis 25:5-6, 24:36)

It should also be pointed out that James does not say Abraham had only one son, and the book of Hebrews uses the phrase "only begotten" (Greek word monogenes[2]) to reference inheritance specifically.

As for Genesis 22:2, at the time Abraham had only two children, Isaac and Ishmael, and Ishmael had been sent away with Hagar for mocking Isaac (Genesis 21:9-21), effectively disinherited. Thus in Genesis 22 God referred to Abraham having only one son, given the disassociation of the other, and the fact that Isaac alone was considered an heir, the other a servant. Paul in Galatians 4 points to all of this, drawing a distinction between two covenants, the Law and that of faith, as symbolized by Ishmael and Isaac respectively.

Verse 16

The ReasonProject lists the following as a Bible contradiction with the headline "How old was Abram when Ishmael was born?"[3]

This allegation has been made for centuries, as has the answer.[4] Genesis 11:26 just shows the oldest son was born when Terah was 70 years old, not necessarily Abraham. Abraham is just mentioned first in the passage due to his importance to the Jewish people, not because he was born first. The evidence indicates Terah was likely born first, followed by Nahor. The three were not triplets.

Abraham left Canaan at age 75 after his father died (Genesis 12:4) and Terah died at age 205, so Abraham was born when Terah was roughly 130 years old. Haran was the firstborn when Terah was 70 years old, so Haran would have been 135 years old by the time Terah died, had he lived that long. Haran actually died before their father Terah did, and before Abraham and Terah even left Ur. (Genesis 11:28) Haran's son Lot appears to have been around Abraham's age, possibly even several decades older, and they traveled to the Promised Land together. (Genesis 12:4-5)

Nahor was likely between Terah's age of 135 and Abraham's age of 75 when Terah died. He ended up marrying his brother Haran's daughter, Milcah (Genesis 11:29), and may have been age 90-100 when Abraham left (which in those days was roughly middle-aged - Genesis 11:19-23). This is supported by the fact that Nahor began having children before Abraham did, 12 male children and possibly an equal amount of female children, probably 20-30 children in all. (Genesis 22:20-24)

At any rate, there is no contradiction, just a misreading of Genesis 11:26 by the critic. The evidence strongly supports Abraham having been born the youngest of his three brothers.
