When Leah had her fourth child she named him Yehudah, saying, "HaPaam Odeh Es Hashem" - "This time I must thank Hashem". Rashi asks, why is it specifically by this child that she had to thank Hashem? He explains, Leah knew that Yaakov would have 4 wives and 12 children. According to the calculation, it comes out to 3 children per wife. Therefore, when Leah had her forth child she said, "HaPaam Odeh Es Hashem" - "This time I must thank Hashem" - As Rashi explains , "ShNatalti Yoser MiChelki" - "For I have received more than my portion."
There is a pshat that it is for this reason, the Jewish Nation is known by the name "Yehudi". Since every Jew must look at what his lot is in this world and say, "Natalti Yoser MiChelki" - I have received more than my share... More than I deserve!!.
