Jesus likely alluded to Zechariah’s prophecies, when he said, “And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.” [Luke 21:20]
He continued, “Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. For these be the days of vengeance, that all things which are written may be fulfilled.”
Rivers bring the water from places where the rain falls, or from high snowy mountains, to places that normally receive very little rain. The prophetic rivers are metaphors. Rain represents God’s word, and the prophetic rivers are streams of God’s revelations, themes of knowledge that extend throughout the Bible. Isaiah said,
For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
The rivers depict themes of the gospel, and they are parables, that illustrate how God’s promises work out through the ages.
The Temple-River of Ezekiel 47:1-12 implies that there is a land through which it flows, and which is healed because of it. What land is it? Not the literal territory of Canaan. It may be the better land mentioned in Hebrews 11:16.
The story of Moses striking the rock in the wilderness which brought forth water has a profound significance, and the theme of water and rivers as symbols of the Spirit flows like a river throughout both the Old and New Testaments. The Jerusalem temple was built above the site of a spring, called Gihon, which was also the name of one of the rivers in Eden. Solomon was crowned king there. [1 Kings 1:32-35]
The land of Canaan was a type and a shadow of better land, to which Christians have come, as taught in the New Testament. [Heb. 11:16; 12:22] Paul said that the experiences of the Israelites recorded in the Old Testament were written for our examples, and for our admonition. Peter said the prophets ministered, not to themselves, but unto us, that is, the saints, or the New Testament church. The prophets, he said, wrote about the gospel, (they “prophesied of the grace that should come unto you”) and they wrote by the spirit of Christ which was in them. [1 Peter 1:9-12]
The prophecy of Ezekiel chapter 34 distinguishes between the mountains of Israel, and the mountains of other lands.
Ezekiel 34:6 says, “My sheep wandered through all the mountains, and upon every high hill: yea, my flock was scattered upon all the face of the earth, and none did search or seek after them.”
God’s sheep are scattered upon the face of the earth, in tens of thousands of sects and denominations, and ministries, with many different beliefs.
In his commentary on Ezekiel, George Currey (1816-1885) discussed the relationship between Ezekiel and the Apocalypse of John, and he pointed out some striking differences.
One of the ways the accounts differ is in their respective descriptions of God’s throne. Currey notes some differences between the accounts in the following paragraph. 
Isaiah said in the last days, referring to Judah and Jerusalem, that the mountain of the Lord’s house would be raised up, to the top of the mountains, and exulted above the hills.
The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem.
And it shall come to pass in the last days, that the mountain of the Lord’s house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.
When we compare this with Ezekiel’s prophecy about the river flowing from the house of the Lord, a paradox appears. Any tectonic event that would elevate Jerusalem in a literal sense, would increase the slope in the surrounding area. But in Ezekiel’s description, the river in the vicinity of Jerusalem is shown to have a very gentle gradient, comparable to that of a football field, where a minimal slope is needed for drainage. In about half a mile, the depth of the river increases by only about three feet. [Ezek. 47:1-7]
