The first word in the Doctrine and Covenants is "HEARKEN".
Here is a talk from Pres. Russell M. Nelson where he talks about the word Hearken: https://www.churchofjesuschrist.org/study/general-conference/2020/04/45nelson?lang=eng
The very first word in the Doctrine and Covenants is hearken. It means “to listen with the intent to obey.” To hearken means to “hear Him”—to hear what the Savior says and then to heed His counsel. In those two words—“Hear Him”—God gives us the pattern for success, happiness, and joy in this life. We are to hear the words of the Lord, hearken to them, and heed what He has told us!
