Deuteronomy 31:25 Meaning and Commentary

Deuteronomy 31:25

That Moses commanded the Levites
These were not the common Levites, but the priests who were also Levites, to whom the law was given, ( Deuteronomy 31:9 ) ; and none but they might touch the ark, or go so near it as, they are bid to do, to put the law on the side of it; so Aben Ezra; it follows,

as the priests are said to do, (See Gill on Deuteronomy 31:9); for though in journeying the Kohathites carried it, yet not until it was covered by the priests, for they must not touch it; as these must do when they put the law on the side of it, as they are ordered in ( Deuteronomy 31:26 ) .

saying;
as follows.
