The God of Abraham, The God of Isaac, and the God of Jacob

Jacob was 120 when his father Isaac died. How old was Isaac when his father Abraham died?

Here is a clear, precise breakdown:

1️⃣ Jacob was 120 when Isaac died (Gen 35:28-29)

Isaac died at 180 years old (Genesis 35:28).

Thus:

> If Jacob was 120 when Isaac (180) died,
Jacob was born when Isaac was years old (Genesis 25:26, consistent).

2️⃣ Isaac’s age when Abraham died:

Abraham died at 175 years old (Genesis 25:7).

Isaac was born when Abraham was 100 years old (Genesis 21:5).

Thus:

> At Abraham’s death (175), Isaac’s age = years old.
