Josiah was one of the youngest king to rule, as of 8 year, he started to rule. Josiah offered the best Passover sacrifice but made a mistake to stop the King of Egypt, Neco from going to Carchemish on the river Euphrates.
Josiah tried to stop him (Neco) even when Neco told him his business was not Josiah concern. And that God had given him the right to go to battle and that if Josiah opposed him, he was opposing Gods will. Sometimes, we have to know what battle to fight and which one to let go off. Of course Josiah the then King of Judah, did not listen and got shot and died. He was rushed back and was buried. His story was a lamentation for all to read.
