There was a treasury of the temple. And what is in the treasury? Gold, silver and all the donations, all the tithing. The safest place in every city was in their main temple. The Temple of Saturn in Rome was the treasury of the Roman Empire, and the walls of the temple of Herod were plated with gold. Laban, as the commander of the city guard, might have had charge over the treasury, which would also have contained the sacred records. Laban’s house would have been right near the temple.
