Zebulun the 10th child of Jacob and 6th of Leah, Dinah the 11th child of Jacob and the 7th of Leah.

Deuteronomy 33: 18 About Zebulun he said: “Rejoice, Zebulun, in your going out,

19 They will summon peoples to the mountain and there offer sacrifices of righteousness; they will feast on the abundance of the seas, on the treasures hidden in the sand.”
Genesis 49:13 “Zebulun will live by the seashore and become a haven for ships; his border will extend toward Sidon. (NIV)
