I only replied to this because of your signature "have you not read what David did?"What's interesting is that Romans 13 describing the biblical definition of true government does not mention breaking laws or committing crimes, but doing good and evil. The only authority any government has is derived from good and evil: they only have the authority to say No to what God has said No to. God says, "Do good, and thou shalt have praise of the same." So when you marry more than one wife, and someone's not happy, that's not your true government talking with authority from God, just confused or outright evil people who have far overstepped rightful governing into oppression and dictatorship, which we may obey for the same reason Jesus paid some token tribute money, though he told Peter it was actually not right that it was asked for.
And for those who talk about things like traffic regulations, here's a thought: owning roads has nothing to do with bearing the sword against evildoers: roads should be private property, and as such if the owner allows you to come on his land and use his road, he has the right to set any terms and conditions he wants, even saying that only pink cars are allowed on his road. But really once private companies have the roads, they have to compete with each other to make both safe and easy to follow regulations, or else they go out of business.
This is again a case of pakuach-nefesh (life-risk) where rabbis & Yeshua concurs, it's ok to break almost any Law of G-d to save a life; in David and his hungry soldiers' case, it's their own lives.
A weak soldier with no energy is a dead soldier. Sorry if this is in the wrong thread, I just wanted to respond to your signature and it's in the same thread where I discussed life-risk in interpreting Paul; I hope that's OK.
