I am a big fan of "quotes". I have a file on my computer full of quotes and periodically will be uploading my favourite ones. Hopefully there will be many more coming shortly. If you have any favourite quotes of your own, please email it through with the subject line set to "quote".
"Your eye shall show no pity on them (Deuteronomy 7:16). We learn that Israel acted against its merciful nature [since otherwise this command would not have been necessary]. Even though the seven nations were despicable as a result of their abominations and had declared war on Israel after being asked for peace, the natural pity and forgiveness in the hearts of the people of Israel overcame them, and they acted only because of God’s command—not as, heaven forbid, those who take pleasure in war and aggression." – Chazon Ish (Teharot, 299a)
