Levitical service and the fellowship of the temple servants
The number 220 appears in the Bible in connection with Levitical service and temple activity. In 1 Chronicles 15:6, 220 Levites from Merari's clan are mentioned under the leader Asaiah, who were among those gathered to bring the Lord's ark of the covenant to Jerusalem. In Ezra 8:20, 220 temple servants (netinim) are noted, whom David and the leaders had given for the service of the Levites, and who returned from exile. Both occurrences link the number to groups of people dedicated to holy service—either as Levites in a temple procession or as temple servants maintaining the practical functions of worship. The number 220 thus points toward collective service in God's house and the community that surrounds the worship of the Lord. The Nethinim (temple servants) mentioned in Ezra 8:20 were a distinct class of servants at the temple. According to tradition, they were originally appointed by David to assist the Levites and continued their service after returning from the Babylonian exile. The number 220 is known in the history of mathematics as the smallest number in a pair of so-called amicable numbers (220 and 284), where the sum of the proper divisors of each number equals the other. This was noted by medieval Jewish philosophers but holds primarily mathematical rather than theological significance. The clan of Merari was one of the three main branches among the Levites (along with Kohath and Gershon). They were responsible for carrying and maintaining parts of the tabernacle's structure, such as planks, beams, and pillars (Num 4:29–33).*
