The number of men from Aaron's priestly lineage under Jehoiada who joined David at Hebron
The number 3700 appears in 1 Chronicles 12:28, where Jehoiada is described as the leader of Aaron's line with 3700 men who joined David in Hebron to transfer Saul's kingdom to him (1 Chron 12:24). That such a large number from the priestly lineage supported David underscores the divine legitimacy of his kingship. The composition of the number—37 times 100—can also be seen in light of the fact that 37 is a number with symbolic weight in biblical context, while 100 often represents a complete unit. That it was precisely priests and Levites who mobilized in this number shows that David's kingdom had broad support from the spiritual leadership in Israel. In the Jewish calendar, the year 3700 corresponds to approximately 60 CE, which falls within the decade before the destruction of the Second Temple in 70 CE. Although this is an interesting historical connection, the number 3700 itself is not attributed any symbolic value in relation to this event. Jehoiada is mentioned as leader (nagid) of Aaron's lineage, a term indicating a military-administrative leadership role rather than a purely cultic function. This shows that the priestly class also had a political and military dimension in ancient Israel. The listing in 1 Chronicles 12 of the warrior groups who came to David at Hebron serves a theological purpose: to show that all Israel—all tribes and classes, including the priesthood—stood behind David's kingship as God's chosen one.*
