Or HaChaim on Deuteronomy 13:13/אור החיים על דברים י״ג:י״ג

1לשבת שם לאמור, "in which to dwell, saying, etc." Moses uses the word לאמור. According to Ketuvot 110 that it is a positive commandment to live in what used to be the land of Canaan, we must read the verse as if the words לשבת שם לאמור had been written in the sequence לאמור לשבת שם.

2We also need to analyse why the Torah used the apparently superfluous word אנשים in verse 14 when all that was necessary was for the Torah to write יצאו בני בליעל, "lawless people have emerged, etc." I would have known that what are meant are "men." If one were to argue that the word אנשים is in contrast to minors, there is no need to write this as minors are not subject to punishment. Apparently, by writing the word אנשים, the Torah wanted to inform us that the people in question used to be righteous people, צדיקים. According to Bamidbar Rabbah 16 the word אנשים always refers to righteous people. Moses says that as soon as they depart from their normal lifestyle they lose their status and are immediately described as בני בליעל.

3The Torah also teaches that although you have not had solid evidence that the people accused of having gone out to cause others to serve idols have indeed done so, it is your duty to start an immediate investigation of the rumours.
