And you will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; indeed, you will flee just as you fled before the earthquake in the days of Uzziah king of Judah. Then Yahweh, my God, will come, and all the holy ones with Him!
Zechariah 14:3 Then Yahweh will go forth and fight against those nations, as the day when He fights on a day of battle.
Zechariah 14:4 And in that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley so that half of the mountain will move toward the north and the other half toward the south.
Zechariah 14:5 And you will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; indeed, you will flee just as you fled before the earthquake in the days of Uzziah king of Judah. Then Yahweh, my God, will come, and all the holy ones with Him!
Zechariah 14:6 And it will be in that day, that there will be no light; the luminaries will dwindle.
Zechariah 14:7 And it will be a unique day which is known to Yahweh, neither day nor night, but it will be that at evening time there will be light.
The verse centers on "flee", "valley", "mountains", "reach", "azel", and "indeed". It is saying that the verse draws attention to "flee" and "valley", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "And in that day His feet will..." into verse 6's "And it will be in that day...", so "flee" and "valley" belong inside that flow. In Zechariah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "flee" and "valley" with trust shaped by these words, not by a vague optimism outside the passage.
