A.T. Robertson Commentary Revelation 11:14

"The second Woe is past: behold, the third Woe cometh quickly." — Revelation 11:14 (ASV)

Is past (απηλθεν). Second aorist active indicative of απερχομα. See 9:12 for this use and 21:1,4. The second woe (η ουα η δευτερα) is the sixth trumpet (9:12) with the two episodes attached (10:1-11:13).

The third woe (η ουα η τριτη, feminine as in 9:12) is the seventh trumpet, which now "cometh quickly" (ερχετα ταχυ), for which phrase see 2:16; 3:11; 22:7,12,20. Usually pointing to the Parousia.
