The answer is: 30

Deut 34:8

In Deuteronomy 34:8, we see a profound moment where the people of Israel mourn the death of Moses for thirty days. This period of mourning reflects not only the grief of loss but also the kind of respect and honor Moses commanded as a leader. He was their guide, bringing them through forty years in the desert and leading them toward the Promised Land—his absence was profound.

Biblically, the practice of mourning itself is a time-honored tradition. In ancient cultures, including those described in the biblical text, mourning periods led to public expressions of sorrow through rituals and gatherings. It's fascinating to think about how this tradition echoes in today’s world. Many cultures still engage in formal periods of mourning that bind communities together, paying tribute to those who have assumed significant roles in their lives.

Also interesting is the symbolism encapsulated in the thirty days. In ancient Hebrew thought, the number 30 can hint at a mature understanding of time. They consider it the time significant enough to reflect, appreciate one's impact, and prepare for a new chapter ahead. After Moses's death, the people faced a transition to new leadership under Joshua, indicating not just an end but also a beginning—an essential reminder that every ending births the potential for a new journey.
