Then there shall be a place
 Fixed and settled, and will be known to be the place: 
 which the Lord your God shall choose, to cause his name to dwell there:
 where he himself would dwell, and where his name would be called, and he would be worshipped: 
 thither shall ye bring all that I command you, your burnt offerings and
 your sacrifices, your tithes, and the heave offerings of your hands;
 of which (See Gill on  Deuteronomy 12:6) 
 and all your choice vows which ye vow unto the Lord;
 or, "the choice of your vows" F7; which, as Jarchi observes, was brought of their choicest things, as they ought to be; see ( Malachi 1:14 ) .
