23:26 Therefore the Leviim need not carry the Mishkan
In anticipation of the construction of the Beit Hamikdash in Yerushalayim, David counts the Leviim and assigns them a new role. Now that the house of God will find its permanent resting place in Yerushalayim, the job of carrying the Mishkan and the holy vessels, which had been assigned to the Leviim in the desert, is no longer relevant. They are therefore assigned other tasks; they are to assist the priests in the Temple service, serve as the gatekeepers for the Temple, and sing daily praises to the Lord. However, each Levi is to serve in the Beit Hamikdash for only one week out of every twenty-four (see chapter 25). The rest of their time, the members of the tribe of Levi have another highly significant job. They are to become the spiritual leaders of the Children of Israel by serving as officers, judges and teachers. As Moshe had blessed the tribe of Levi before his death, “They shall teach Your laws to Yaakov And Your instructions to Yisrael” (Deuteronomy 33:10). It is for this reason that they are not given their own portion in the Land of Israel, but instead are scattered among all the other tribes (see Joshua chapter 21). In this way, they are able to have an impact on the entire nation, providing the spiritual guidance essential for the Children of Israel to accurately represent God to the rest of the world.
