Neither was Jerusalem a kingdom.
If Jerusalem did not represent the kingdom of God, why did Jesus say, "Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof." Matthew 21:43

Revelation 17:18 "And the woman whom you saw is that great city which reigns over the kings of the earth.
What is the ONLY city with the scriptural authority to "reign over the Kings of the Earth?"
JERUSALEM
Earthly Jerusalem, by Divine right and calling, was the preeminent city among all nations. The Hebrew/Biblical understanding of Jerusalem is that she is the "Chief of the nations" (Jeremiah 31:7; Ez 5:5), the Queen city of the earth (Lam 1:1/Rev 18:7). She, by Divine right and covenant, was appointed as the head of all nations (Deut 26:19; Deut 15:6; Deut 28:1,10-13), and the gentile kings recognized God's dwelling was at Jerusalem with the Hebrews (1 Ki 10:24; Luke 11:31; Ezra 1:2; Dan 2:47, 3:28-29, 4:1-3, 4:17, 4:34-37; Ezra 1; Ezra 4-7; Ezra 7:15,23).
The Governor of all nations (Ps. 22:28) lived in Jerusalem in his House (Ez 7:15,23), and all the kingdom, power and might over earth was His (1 Chron 29:11-12). Indeed, all kings receive their power to rule from that Divine King (Rom 13:1-2,6; John 19:11; 1 Pet 2:13-14,17; Ez 1:2; Dan 1:1-2; Dan 2:20-21; Dan 2:37-38; Dan 2:47, Dan 3:28-29; Dan 4:1-3,17,34-37.).
Without question, Jerusalem was the ONLY City with the Divine Right to "Reign over the Kings of the Earth"
The "Woman" of Revelation, who is the "Great City" that "reigns over the Kings of the Earth" can only be Jerusalem.
