Allow no one to come into the house of Yahweh, except for the priests ... serving

This double negative emphasizes that the priests and Levites were the only people whom the assembly was to allow into the house of Yahweh. Alternate translation: "The only people you may allow to come into the house of Yahweh are the priests ... serving" (See: rc://en/ta/man/jit/figs-doublenegatives)

Allow no one to come into the house of Yahweh

"Do not allow anyone to come into the house of Yahweh"

But all the other people must obey the commands of Yahweh

It may be helpful to state that command. Alternate translation: "All the others must remain in the courtyard, obeying what Yahweh has commanded" (See: rc://en/ta/man/jit/figs-explicit)
