The book is...a vision of a society under the sovereignty of God and of Israel as an am kadosh, a phrase that appears four times in the book...

In fact, the phrase עם קדוש or עם קדש appears five times in Deuteronomy: 7.6, 14.2, 14.21, 26.19 and 28.9. In the final instance there is a prefixed ל, but surely this is not a reason to discount it.
