For it is written......

Right wing Knesset member, Arieh Eldad says that today's terrorist attack in Jerusalem is a direct result of immoral deals made with the enemy.

I think his words are well supported by
Devarim (Deuteronomy) Chapter 7:

"When the Lord your God takes you into the land where you are going, which is to be your heritage, and has sent out the nations before you, the Hittites and the Girgashites and the Amorites and the Canaanites and the Perizzites and the Hivites and the Jebusites, seven nations greater and stronger than you;

And when the Lord has given them up into your hands and you have overcome them, give them up to complete destruction: make no agreement with them, and have no mercy on them"

My italics ... G-d's commandment.

They should know better!
