most of these were dealing with different situations such as war,punishment for following other gods breaking covenants,
so these are like compareing apples to oranges........Abortion is like Israel passing their children through the fire in the worship of molech and not the carrying out of justice or puting sin out of the camp or doing away with an enemy in the promised land
Deu 18:10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch,
2Ki 17:17 And they caused their sons and their daughters to pass through the fire, and used divination and enchantments, and sold themselves to do evil in the sight of the LORD, to provoke him to anger.
Jer 32:35 And they built the high places of Baal, which are in the valley of the son of Hinnom, to cause their sons and their daughters to pass through the fire unto Molech; which I commanded them not, neither came it into my mind, that they should do this abomination, to cause Judah to sin.
notice the "NEITHER CAME IT INTO MY MIND" part of that verse this i feel is proof of why abortion is wrong
