Which do not apply today under the New Covenant, but do serve as a reflection of Gods Character. I can see how the stone your children commandment would disturb you, it disturbs me as well (greatly). But since I believe in a God who is infinitely good, I accept he has a good purpose for everything, including this harsh commandment. The Law was meant to drive people to Christ as the fulfillment of the law - he bore the punishment for disobedience so that I do not have to.
