Lehi

Josiah was only 8 yrs old when his father was assassinated by the same "priests" who made Josiah "king", and placed him "under their protection".

12 years later King Josiah starts his "reforms" (2 Chronicles  34:1-3) which the Bible extols as virtuous/holy/praise worthy => BUT  "the word of the Lord came [to Jeremiah] in the days of Josiah the son of Amon king of Judah, in the thirteenth year of his reign." (Jeremiah 1:1-2) => NOT a good sign. 

Only one year into Josiah's great reform, God sends Jeremiah to tell the people

• "Hath a nation changed their gods, which are yet no gods? but my people have changed their glory for that which doth not profit."

•  "my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water"

• "Hast thou not procured this unto thyself, in that thou hast forsaken the Lord thy God"

Jehovah (YWH), and his prophet, are clearly NOT a supporters of these Deuteronomistic reforms (see Jeremiah chapters 2-3-4)

There are enough scriptures to support the hypothesis that after King came of age, Lehi ran afoul of his Deuteronomistic "reforms", much like Jeremiah had.

By hebrew law, Lehi MUST have been at least 30 yrs old (duh... has 4 teenage kids) and married in order to preach, which he does (1 Nephi 1:18)... 

So, he has lived at least 18 yrs under King Josiah (28 yrs if he was 40 yrs old) and all 31 yrs of Josiah's reign, if Lehi was more than 43 years old when Zedekiah took the throne.

So, when Lehi told "the Jews" that:

• he had seen VISIONS

• had SEEN GOD

• he could PROPHESY the future of Jerusalem

He had violated the first three tenents of Deuteronomistic theology, and under the law-of-moses... must be stoned, so of course they tried to kill him (1 Nephi 1:18-20)
