Like I said in the previous answer , It was not uncommon for a son to become co-ruler especially when his father is in danger of dying .
Jehoiakim,Jehoiachin's father, was waging war against Babylon, so he was clearly in danger of dying. It would make sense to place his son as a co-ruler in order to ease the transition of power upon his death in the future.
In 2 Kings 15:30 it says " In the 20th year of Jotham, son of Uzziah"....
Clearly this is referring to his age not the number of years in his reign,because it refers to him as "Jotham , son of Uzziah"and not as a king. Also a few verses later in 2 Kings 15:33 it says " Jotham was 25 years old when he became king and he ruled 16 years in Jeruselam", so this shows a passage of time following the reference to Jotham in verse 30 and then his ascension as king in verse 33.
He clearly was 22 because of his father was 40 when he died, so he could not be older than his father.
As for the verse mentioning him being 42 years old--if you read the next verse it says "Ahaziah followed the ways of Ahab's family, because his mother encouraged him to do wrong. Ahaziah did what the Lord said was wrong, as Ahab family had done." this probably means that it was 42 years that his family or the house of Ahab(who he was descended from) was in power when he became king.
You are obviously getting these questions from off the internet--otherwise you would know better than to post a silly question like this one.
God split the Nation of Israel into 2 nations(Judah and Israel) because of the disobedience of King Rehoboam , Asa's father.
Asa was the king of Judah and Ommri was the king of Israel.
The 30 talent difference can most likely be accounted for by King Hiram, of Tyre, lending his men to Solomon to bring back the gold because most of Solomon's men were otherwise occupied in other types of work and Hiram men where more skilled at sailing the ships used to bring back the gold. The men brought back 450 talents(17tons) of gold and Hiram probably charged him 30 talents(a little over 1 ton) for the labor, so Solomon's gross totaled 450 and his net profit was 420.
They could both be true .
Each verse probably is talking about a different period of time in Solomon's reign. In 2 chronicles it talks about Solomon being visited by the Queen of Sheba,but 1 kings does not .
It was not uncommon for a king to change the size of his army depending on whether he was in a period of peace or war. King Solomon 's reign was mostly peaceful except for the beginning, so it would make sens for him to have a large army.
Both are correct .
In 2 Samuel 21:1 it says (1) During the reign of David, there was a famine for three successive years; so David sought the face of the LORD. The LORD said, "It is on account of Saul and his blood-stained house; it is because he put the Gibeonites to death." This shows that Israel was already going through 3 years of famine .By the time God gave David the choice of 3 years of famine another year had passed ,so add 3+1+3 and you get 7 years of famine.
This might mean that he captured 7,'000 and let 700 live.
Like I said before the bible is God true and inerrant word.
You can't prove the bible wrong . You can only prove it true.
I hope you this helps you to come at least a little bit closer to believing in the one and only almighty God. His wonders are beyond words . Peace
