"Yacov will be happy, and Israel will rejoice"[i] The name Yacov refers to the Jewish man while he is wrestling with life's many problems, whatever they may be. When he overcomes these problems he is no longer called Yacov. At this stage he is called by his greater name, Israel. Israel is greater than Yacov, and his rejoicing is greater than Yacov's happiness. Indeed, two signs of a great person are humility, and great joy.
[i] Psalms 14:7
