Most of your Bible was written by Civil Rulers, or is about Government.
At the time of the Exodus, Pharaoh was the governor of Egypt. Moses was the governor of Israel. People often assume that the Bible is all about religion, and not government. The pubic is led to believe that Christians and religious people do not belong in government. That Clergy are not to speak out from the pulpit about political issues.
Moses was the head of the nation's government. (Aaron was the High Priest and head of the church.)
Joshua succeeded Moses as governor of Israel.
After Joshua the Judges ruled in Israel.
Kings and their kingdoms followed the Judges system of government. Saul was the first king and Zedekiah the last. After many wars the King of Babylon conquered the remaining Israelites.

In the Bible's books of Ezra and Nehemiah we read about the restoration of the Israelite government in Palestine many years later. What was Nehemiah's title? The answer is in the Bible's Book titled Nehemiah.
Here we are 500 pages into a 1130 page Bible and, thus far, it is almost all written by men in government, about civil rulers or it is about the history of national governments.
Now we are at page 638. In the remainder of the Old Testament we have books about the prophets such as, Isaiah, Jeremiah and Ezekiel. The Prophets were sent to the governments of the nation. They delivered God's word to the king. Many times the king didn't like what he heard and the prophet had to leave town, hide, or be put in jail.
Then we come to the New Testament. The Gospels are about the Kingdom of Heaven. In Acts 9:15, Paul was commissioned by Christ to bear His name before kings. Revelation 5:10 reads, ..and we (Christians) shall reign on the earth.
So, in addition to all the 'religious' content, the New Testament also talks about government. In fact, at least 71% of your Bible is about government!
