The Name of Hashem in the Name of Yehudah

Why did the Holy One, Blessed is He, see fit to give the kingship to Yehudah of all the brothers? The letters of Hashem's Name are inscribed in the name Yehudah, and the Holy One, Blessed is He, honors His Name. The letter daled of Yehudah, which is not in His Name, stands for Dovid HaMelech, who bound himself to Hashem's Name more than all the people of the world. Thus it is written, "They shall seek Hashem their God and David their king" (Hoshea 3:5).
