Revelation 9:12-13

9:12 The first woe has passed, but ¹  two woes are still coming after these things!

9:13 Then ²  the sixth angel blew his trumpet, and I heard a single voice coming from the ³  horns on the golden altar that is before God,

[9:12]  ¹ tn Grk “behold.” Here ἰδού (idou) has been translated as “but” to indicate the contrast present in the context.

[9:13]  ² tn Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the vision.

[9:13]  ³ tc ‡ Several key mss (Ì⁴⁷ א¹ A 0207 1611 2053 2344 pc lat sy^h co) lack the word τεσσάρων (tessarwn, “four”) before κεράτων (keratwn, “horns”). The word seems to have been added by scribes because a “horned” altar (described in the OT [Exod 30:2, 10]) could have only four “horns” or projections at the corners. NA²⁷ includes the word in brackets, indicating doubts as to its authenticity.
