Genesis 6:3

The context

This comes in the prose preamble to the flood story, after the strange episode of the sons of God and the daughters of men, and just before the notice that human wickedness was great. God is speaking, and the sentence links his spirit, human flesh, and a number of years.

What it establishes

God is presented as setting a boundary on human life or on his patience with it. Either way the verse marks a divine decision that changes the terms of the story that follows.

What it does not establish

The 120 years is disputed. It may be a cap on lifespan, a countdown to the flood, or a period of probation; the Hebrew is compressed enough that no reading is forced, and the verse gives no biological rule.

• So Adam and Eve lived for 900+ years and Methuselah celebrated 930 years. Is it just me, or do these claims not strain credulity beyond its limits?
