I am the Root and the Offspring of David: Jesus confirms the message of Revelation (compare John 21:24). He is the Root of David (see Revelation 5:5; Isaiah 11:10) and a descendant of David (see Ezekiel 37:23–24; Romans 1:3).
The morning star was a title for the Messiah (see Numbers 24:17; 2 Peter 1:19; compare Luke 1:78–79).
