You left out the remaining verses of Zechariah chapter 14 that explains what that scriptures is about. Sometimes it's best to read everything and not just a single verse because it helps readers understand not everything written in the bible is about 70AD.
Jericho, where did you get the impression that I have not read all of Zechariah? I have been at this for over half-century. I am not claiming that I understand it (not by any stretch of the imagination), but I have certainly read it.
.
2 And I will gather all the Gentiles to Jerusalem to war, and the city shall be taken, and the houses plundered, and the women ravished; and half of the city shall go forth into captivity, but the rest of my people shall not be utterly cut off from the city.
3 And the Lord shall go forth, and fight with those Gentiles as when he fought in the day of war. 4 And his feet shall stand in that day on the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave asunder, half of it toward the east and the west, a very great division; and half the mountain shall lean to the north, and half of it to the south. 5 And the valley of my mountains shall be closed up, and the valley of the mountains shall be joined on to Jasod, and shall be blocked up as it was blocked up in the days of the earthquake, in the days of Ozias king of Juda; and the Lord my God shall come, and all the saints with him. 6 And it shall come to pass in that day that there shall be no light, 7 and there shall be for one day cold and frost, and that day shall be known to the Lord, and it shall not be day nor night: but towards evening it shall be light.
8 And in that day living water shall come forth out of Jerusalem; half of it toward the former sea, and half of it toward the latter sea: and so shall it be in summer and spring. 9 And the Lord shall be king over all the earth: in that day there shall be one Lord, and his name one, 10 compassing all the earth, and the wilderness from Gabe unto Remmon south of Jerusalem. And Rama shall remain in its place. From the gate of Benjamin to the place of the first gate, to the gate of the corners, and to the tower of Anameel, as far as the kings winepresses, 11 they shall dwell in the city; and there shall be no more any curse, and Jerusalem shall dwell securely.
You posted a series of verses from Zechariah, but you have not shown you understand them, either. For example, from the few I understand, verse 8 is referring to the Comforter --the Holy Ghost--given on the day of Pentecost. These are some background prophecies:
"For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water." -- Jer 2:13
"O Lord, the hope of Israel, all that forsake thee shall be ashamed, and they that depart from me shall be written in the earth, because they have forsaken the Lord, the fountain of living waters." -- Jer 17:13
"And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:" -- Joel 2:28
Now compare the wording in Zechariah with the words of Christ:
"And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be." -- Zec 14:8
"In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink. He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)" -- John 7:37-39
This was Jesus speaking to his disciples, after the resurrection, and before his ascension to the Father:
"And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence." -- Acts 1:4-5
This is when the Holy Ghost was given, beginning in Jerusalem, exactly like Zechariah prophecied:
"And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven." -- Acts 2:1-5
.
Now, Zechariah 14:9 was fulfilled upon Christ's resurrection. This is Christ shortly before his ascension:
"And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth." -- Matt 28:18 KJV
And this is Peter on the day of Pentecost:
"Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. For David is not ascended into the heavens: but he saith himself, The Lord said unto my Lord, Sit thou on my right hand, Until I make thy foes thy footstool." -- Acts 2:29-35
Paul also comfirmed that Christ has been reigning since the first century:
"For he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death." -- 1Cor 15:25-26 KJV
"But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom." -- Heb 1:8
Peter, again:
"Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him." -- 1Pet 3:22
Aside from those two verses, and verses 1 through 3, the remainder of the verses are virtually incomprehensible. I would be wary of anyone who claims to completely understand them.
