New Defender's Study Bible Notes
14:5 the earthquake. This earthquake is also mentioned in Amos 1:1, and must have been a terrible catastrophe, to be remembered so long—approximately three hundred years by the time of Zechariah. Geologists have generally confirmed this.
14:5 the saints with thee. When the Lord Jesus—the Messiah—does return at this time, He will, indeed, be accompanied by a host of “saints” (or “holy ones”). These will include both angels and redeemed men and women in their resurrection bodies (see II Thessalonians 1:7, I Thessalonians 3:13; 4:16-17; Revelation 19:7-14).
