Ashkelon will see it and be afraid.Gaza too will writhe in great pain;Also Ekron, for her expectation has been confounded.Moreover, the king will perish from Gaza,And Ashkelon will not be inhabited.

Rejoice greatly, O daughter of Zion!Shout in triumph, O daughter of Jerusalem!Behold, your king is coming to you;He is just and endowed with salvation,Humble, and mounted on a donkey,Even on a colt, the foal of a donkey.

For I will no longer have pity on the inhabitants of the land,” declares the Lord; “but behold, I will cause the men to fall, each into another’s power and into the power of his king; and they will strike the land, and I will not deliver them from their power.”

You will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; yes, you will flee just as you fled before the earthquake in the days of Uzziah king of Judah. Then the Lord, my God, will come, and all the holy ones with Him!

And the Lord will be king over all the earth; in that day the Lord will be the only one, and His name the only one.

Then it will come about that any who are left of all the nations that went against Jerusalem will go up from year to year to worship the King, the Lord of hosts, and to celebrate the Feast of Booths.

And it will be that whichever of the families of the earth does not go up to Jerusalem to worship the King, the Lord of hosts, there will be no rain on them.
