Great. It is even greater to me as our family name identifies us as direct descendants of King David.

@Danial Mahdavi for your information, as you strike me that you like to learn new things. King David had a lot of wives and that made a lot of descendants. His name was David Ben Yishai דוד בן ישאי, David Son of Yishai. In the old Hebrew it was always the name of the child son of name of the father. Because of the amout of descendents, the people in Jerusalem gave them a tag which is the first 3 letters of King David's family name. It דבי in Hebrew and دبي in Arabic. The English equivalent is DBY, but the British distorted it as usual. If you ever noticed, the name of Dubai in Arabic is the same as my family name. The reason is that area was established by someone from my family in the late 19th century. Another piece of info. When the great Cyrus freed Babylonian Jews and allowed them to leave, the majority stayed. Their main reason was the King in Israel, at the time, was not as per the Lord's dictation. The final King of Israel has to be a direct descendant of King David, and he will eventually become the Mashiah (Messaiah). But the problem was that the Babylonians took all the people of Jerusalem, thus there were no descendants of king David to elect in Jerusalem. But the Babylonian Jews did great things for the planet and humanity during their 2,600+ years of exile.

@Shauna Starcher as a Hebrew user, I would not trust anyone with the name Tousi. In Hebrew it is nearly equivalent to ASS.
