'Forty' in the Bible

Just as he mentioned the ark of God, he fell from his chair backwards against the side of the gate. He broke his neck and died, because the man was old and heavy. He had judged Israel forty years.

Saul [was thirty] {years old} at the beginning of his reign, and he reigned [forty-]two years over Israel.

Now the Philistine came forward early and late, and he took his stand [for] forty days.
