John Gill Commentary Deuteronomy 12:14

"but in the place which Jehovah shall choose in one of thy tribes, there thou shalt offer thy burnt-offerings, and there thou shalt do all that I command thee." — Deuteronomy 12:14 (ASV)

But in the place which the Lord shall choose in one of your
tribes
Which tribe is not named, nor what place in that tribe; (See Gill on Deuteronomy 12:5),

there you shall offer your burnt offerings ;
on the altar of burnt offering there placed:

and there you shall do all that I command you ;
respecting sanctuary service, and particularly those things observed in (Deuteronomy 12:6) .
