'During' in the Bible

During the fourth year of the reign of King Darius, a message from the LORD came to Zechariah on the fourth day of the ninth month Kislev.

"Talk to everyone in the land, as well as to the priests. Ask them, "When you were fasting and mourning during the fifth and seventh months for the past seventy years, were you really fasting for me?

They will be like mighty soldiers who trample mud in the streets during battle. They will fight because the LORD is with them, and the opposing horsemen will be confused.

You will run away through my mountain valley, because the valley of the mountains will extend as far as Azal. You will flee, as you fled from the earthquake during the reign of King Uzziah of Judah. And so the LORD my God will come, and all his holy ones will be accompanying you."
