'Forty' in the Bible

So Hazael went to meet him and took a gift in his hand of all of the good things of Damascus, a load [on each] of forty camels, and he came and stood before him. Then he said, "Your son Ben-Hadad king of Aram has sent me to you, saying, 'Shall I recover from this illness?'"

In the seventh year of Jehu, Jehoash became king. He reigned in Jerusalem forty years, and the name of his mother [was] Zibiah from Beersheba.
