“Daystar.” The expression “daystar” (Gr., pho·sphoʹros) occurs once, at 2 Peter 1:19, and is similar in meaning to “morning star.” Such stars at certain seasons of the year are the last stars to rise on the eastern horizon before the sun appears and thus are heralds of the dawn of a new day. Peter’s previous reference to the vision of Jesus’ transfiguration in magnificent glory suggests a relation to his entering into kingly power as “the root and the offspring of David, and the bright morning star [a·sterʹ].”​—Re 22:16; 2:26-28.

The resurrected and exalted Jesus spoke of himself as “the bright morning star” and promised to give “the morning star” to his conquering followers, evidently indicating a sharing with him in his heavenly position and glory. (Re 22:16; 2:26, 28; compare 2Ti 2:12; Re 20:6.)
