The Phrase “the Covenant Path”

The earliest General Conference reference is 2007, in a talk by Elaine Dalton.  She is quoting an article Elder Holland wrote for the 2006 Ensign.

References to the covenant path seem to pick up around then.

Google Ngram

The earliest reference in BYU speeches is to Sister Wixom in 2013
The Covenant Path | Rosemary M. Wixom | BYU Speeches

A date-limited google search suggests a bunch of results prior to 2006, but at least the first page of results were actually from dates much later.

The phrase doesn’t appear in the Journal of Discourses that I can tell.
