If God set the maximum age to 120, then how could Jacob be 130 years old?

At the time of Noah, God said: > **Genesis 6:3 NIV** > Then the LORD said, “My Spirit will not contend with humans > forever, for they are mortal; their days will be a hundred and > twenty years.” Now, later on, we have the account of Jacob and his sons. When Jacob moves to Joseph in Egypt, the pharaoh of asks him of his age, to which he replies: > **Genesis 47:9 NIV** > And Jacob said to Pharaoh, “The years of my pilgrimage are a hundred > and thirty. My years have been few and difficult, and they do not > equal the years of the pilgrimage of my fathers.” Is there any explanation for this? I guess that either you can interpret this as Jacob referring to something else then his true physical age (e.g. "the years of my pilgrimage" having some kind of special meaning), or he might have miscalculated, or God's rule of the maximum age of man might not apply to all, like Abraham, Isaac, Jacob, Moses and other distinguished men of God.
