21:2 And I saw the holy city – the new Jerusalem – descending out of heaven from God, made ready like a bride adorned for her husband.

[19:4]  ¹ tn Grk “creatures fell down.” BDAG 815 s.v. πίπτω 1.b.α.ב. has “fall down, throw oneself to the ground as a sign of devotion or humility, before high-ranking persons or divine beings.”
