Fathers shall not be put to death for their children, nor children put to death for their fathers; each is to die for his own sin.But that's a verse taken out of context! Surely if we read what surrounds it, we'll see that it doesn't apply to the case of undocumented aliens.
14 Do not take advantage of a hired man who is poor and needy, whether he is a brother Israelite or an alien living in one of your towns. 15 Pay him his wages each day before sunset, because he is poor and is counting on it. Otherwise he may cry to the Lord against you, and you will be guilty of sin. 16 Fathers shall not be put to death for their children, nor children put to death for their fathers; each is to die for his own sin. 17 Do not deprive the alien or the fatherless of justice, or take the cloak of the widow as a pledge. 18 Remember that you were slaves in Egypt and the Lord your God redeemed you from there. That is why I command you to do this. (NIV)Yeah, so there is that.
