Descended Masters No. 30/30= Part of the meaning of this No. 30 comes from its symbolization of dedication to a particular task or calling. Aaronic priests were initially dedicated to serving at thirty years of age (Numbers 4:3). God likely chose age 30 because it was when a person reached both physical and mental maturity. As such, they could handle major responsibilities.
John the Baptists' mother was a descendant of the daughters of Aaron and his father was a priest, so he was of priestly descent. He began his ministry at the age of 30 as well. At the age of 30, Jesus Christ began to publicly preach the gospel (Luke 3:23), and his ministry lasted for three and one-half years.
This No. 30 also represents the sacrificial blood of Jesus Christ, as he was betrayed by Judas for thirty silver coins. This act was a fulfillment of prophecy (Zechariah 11:12). When Judas flung the "blood money" he had been paid back into the temple, the priests did not accept it as an offering, but rather decided to buy a potters' field with it. Though they weren't aware of it, what they did was also fulfilling prophecy (Verse 13).
In 30 A.D., Jesus suffered and shed his precious blood as Gods' sacrificial lamb for the worlds' sins.
The Dead Sea Scrolls were discovered in caves on the upper northwest shore of the Dead Sea starting in 1947. Among all the scrolls found over the years, 30 copies of the Psalms have been identified.
The patriarchs Salah (who was a grandson of Shem), Peleg (who lived to see the worlds' continents divided) and Serug (the great-grandfather of Abraham, had their first sons at the age of 30.
The prophet Ezekiel began his book "In the thirtieth year" at age 30, which likely referenced to his prestigious age at the time (Ezekiel 1:1). It's at that time he received his first recorded vision from God known as the "Wheel in the middle of the wheel" or "Wheel within a wheel" vision. Ironically, this kind of describes my Ring Deck as well.
In conclusion, Abraham was promised that if God found at least 30 righteous people in Sodom and Gomorrah, he would not destroy the cities (Genesis 18:30).
