Many of the followers of the Book wish that they could turn you back into unbelievers after your faith, out of envy from themselves, (even) after the truth has become manifest to them; but pardon and forgive, so that Allah should bring about His command; surely Allah has power over all things.

And certainly Allah made good to you His promise when you slew them by His permission, until when you became weak-hearted and disputed about the affair and disobeyed after He had shown you that which you loved; of you were some who desired this world and of you were some who desired the hereafter; then He turned you away from them that He might try you; and He has certainly pardoned you, and Allah is Gracious to the believers.
