'Concerns' in the Bible

“The service of the Kohathites at the tent of meeting concerns the most holy objects.

They are to take care of your concerns and all the responsibilities involved with the tent. But they're not to approach the holy vessels or the altar. That way, neither you nor they will die.

So the elders of Moab and Midian left to visit Balaam, bringing an honorarium with them, and communicated Balak's concerns to him.
