'Serve' in the Bible

"This is what the LORD of the Heavenly Armies says: "If you will live according to my ways, and if you will keep what I have entrusted to you, then you will also administer my Temple, and you will also guard my courtyards. And I will give you access to these who serve here.

Yes, he will indeed rebuild the Temple of the LORD, and he will exalt its majesty by sitting and ruling on his throne. He will serve as priest on his throne, and no contention will exist between them.
