In the Book of Deuteronomy there are certain rules and regulations that govern war. This is important because even though war is a matter of destroying the enemy, soldiers must not loose their sense of being human. Our wars are against each other and not against the world around us. All channels of negotiations must be exhausted before a war is undertaken as can be learnt from Deut. And if it will not make peace with you and make war against you, then you may besiege it.
Poverty is still very much as relevant today as it was to our ancient ancestors.
There are nations who are starving, while others have so much surplus, which they destroy to keep food prices artificially high. That is not to say that wealthy nations must pour their surplus into the 'Third World', but that they must help them to become self-reliant, to give to them enough to halt starvation and help them to help themselves. Social justice is not something that went out of fashion 3,000 years ago, but some thing that holds value for all eternity. The oppression of the poor the down trodden and the defenseless, the abuse the employee in this dog eat dog society are issues that stare us in the face every day. The Mikra condemns judges who take bribes and thus pervert the course of justice.
