14:4 mount of Olives. As Christ ascended from Mt. Olivet, there He shall stand again (Acts 1:11-12).
14:4 shall cleave. The great splitting of the Mount of Olives, beneath which are known to exist even now great fault lines, will probably result from the global earthquake of Revelation 16:18-19.
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).
14:6 that day. The phrase “in that day” refers to “the day of the LORD,” the period when God is judging and cleansing the earth and its inhabitants. It occurs twenty-one times in the book of Zechariah—first in Zechariah 2:11, last in 14:21.
