The number 930 represents Adam's total lifespan according to Genesis 5:5, symbolizing humanity's original life expectancy after the fall.
In Genesis 5:5 it is stated that Adam lived 930 years before he died, making the number a symbol of the first human's complete life cycle and the consequence of the fall—that humanity became mortal. The number 930 thus marks the transition from immortality to mortality and is connected with reflections on human frailty and God's plan for humankind. Adam's lifespan is the first recorded in the Adamic genealogy in Genesis 5, setting in motion the long series of patriarchs' ages, which gradually decline through subsequent generations. In Midrash (Bereshit Rabbah) and Talmud (Sanhedrin 38b), there is a tradition that Adam was originally meant to live for 1,000 years, but in a prophetic vision he saw the soul of King David and voluntarily gave him 70 of his own years. According to this tradition, this explains why Adam lived 930 years (1,000 − 70) and David lived exactly 70 years.*
