to testify to you
Here the word "you" is plural. (See: rc://en/ta/man/translate/figs-you)
the root and the descendant of David
The words "root" and "descendant" mean basically the same thing. Jesus speaks of being a "descendant" as if he were a "root" that grew out of David. Together the words emphasize that Jesus belongs to the family of David. (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-doublet)
the bright morning star
Jesus speaks of himself as if he were the bright star that sometimes appears early in the morning and indicates that a new day is about to begin. See how you translated "morning star" in Revelation 2:28. (See: rc://en/ta/man/translate/figs-metaphor)
