In Deuteronomy 31:9, Moses gives the written law to the priests — here in 31:25 he commands the Levites who carry the ark to place the book beside it.

Joshua 3:3 shows the people following the Levites carrying the ark — the same group Moses commands here.

Joshua 6:12 depicts the priests bearing the ark around Jericho — the very Levites Moses commands here.

Joshua 8:33 shows the Levitical priests carrying the ark at the covenant ceremony — continuing the role Moses assigned here.
