The verse centers on "zadok", "priest", "brethren", "priests", "before", "tabernacle", "jehovah", and "high". It is saying that the verse draws attention to "zadok" and "priest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 38's "and Obed-edom with their brethren threescore and..." into verse 40's "to offer burnt-offerings unto Jehovah upon the...", so "zadok" and "priest" belong inside that flow. In 1 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "zadok" and "priest" with trust shaped by these words, not by a vague optimism outside the passage.
