Star; Zechariah 3:8; 6:12), radiance of the Light eternal (Habakkuk 3:4; Wisdom 7:26; Hebrews 1:3) and Sun of Justice (Malachi 3:20): come, and enlighten those who sit in darkness and in the shadow of death (Ps 107:10; Lk 1:78).

And from Isaiah 9:1 - The people that walked in darkness have seen a great light; on the inhabitants of a country in shadow dark as death light has blazed forth.
