When Jacob blessed his sons before he died, he foretold how the tribes would be based on what the sons had been. Of Zebulun, Jacob said,

“Zebulun shall dwell by the haven of the sea;
He shall become a haven for ships,
And his border shall adjoin Sidon.”
(Genesis 49.13)

Zebulun sounds like he would be a blessing and be blessed. Truly, not only the tribe, but the nation of Israel has blessed the world and received blessings. Pray that you be a blessing and the Lord shall open doors for you to be so.
