Theodoret of Cyrus
David designated the offspring of the renowned Moses to oversee the holy riches. These treasuries were meant to hold not only the spoils acquired from battle but also the offerings made to the Lord.
And Subael the son of Gersom, the son of Moses, was chief over the treasures.
וּשְׁבֻאֵל֙ בֶּן־גֵּרְשׁ֣וֹם בֶּן־מֹשֶׁ֔ה נָגִ֖יד עַל־הָאֹצָרֽוֹת׃
