Jesus rode into Jerusalem in fulfillment of Zechariah 9:9, “Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.” Also, the timing was as prophesied in Daniel 9:25.
Luke 19:41-42, “41 And when he was come near, he beheld the city, and wept over it, 42 Saying, If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! but now they are hid from thine eyes.” It is as if scales have covered their eyes and they were and are blinded to Jesus as Messiah.
Saul was spiritually blinded by the law to the point that he persecuted the believing Jews. On the road to Damascus, Saul had an encounter with the glorified Jesus and was blinded physically. Ananias was sent to Saul by Jesus, "that thou mightest receive thy sight, and be filled with the Holy Ghost." Act 9:18, “And immediately there fell from his eyes as it had been scales: and he received sight , and arose, and was baptized.” Perhaps foretelling of when the fullness of the Gentiles come in and the scales drop from the eyes of the Israelis.
Matthew 23:37, “O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!”
Jesus held the Jews responsible to know the time of thy visitation. Matthew 23:38-39, “38 Behold, your house is left unto you desolate. 39 For I say unto you, Ye shall not see me henceforth, till ye shall say, blessed is he that cometh in the name of the Lord.”
Romans 11:25 speaks to how long the blindness would last. “For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.” The fullness of the Gentiles is when the Gentile bride is completed and caught up/ Raptured from the earth; then God will resume His dealings with Israel.
Ezekiel 37 and the “Valley of dry bones” is prophetic of the restoration of the unbelieving Israel that occurred in the 20th Century. Ezekiel 36:22, “Therefore say to the Israelite's, ‘This is what the Sovereign LORD says: It is not for your sake, people of Israel, that I am going to do these things, but for the sake of my holy name.” God cannot abandon Israel without breaking His Word. God will protect the Jews as prophesied in both Ezekiel 38 and Psalm 83.
During the tribulation many Jews will be killed by the Antichrist and his minions, nevertheless, a remnant will escape to Petra. According to Zechariah, the remnant “shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son.” Then the scales will drop from their eyes and they will be brought into the Kingdom.
As Christians we are required to know the time in which we live, to be like the Sons of Issachar.
