'Forty' in the Bible

But the former governors that were before me had been chargeable to the people, and had taken of them bread and wine, besides forty shekels of silver: even their servants bore rule over the people. But I did not so, because of the fear of God.

Yea, forty years didst thou sustain them in the wilderness; they lacked nothing; their clothes grew not old, and their feet swelled not.
