Revelation 12:3

Then ¹  another sign appeared in heaven: a huge red dragon that had seven heads and ten horns, and on its heads were seven diadem crowns. ² 

Isa 9:15; Isa 27:1; Isa 51:9; Da 2:42; Da 7:7,8,20,24; Re 12:1; Re 12:4,9,17; Re 13:1,3; Re 13:1; Re 13:2,4; Re 16:13; Re 17:3,4; Re 17:3,7,12,16; Re 17:9,10; Re 20:2

¹ tn Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the vision.

² tn For the translation of διάδημα (diadhma) as “diadem crown” see L&N 6.196.

sn Diadem crowns were a type of crown used as a symbol of the highest ruling authority in a given area, and thus often associated with kingship.
