"from one end of the earth to the other": the sun and the moon, which go from one end of the earth to the other.
(Devarim 13:9) "You shall feel no affection for him": Because it is written (Vayikra 19:12) "And you shall love your neighbor as yourself," I might think that you shall love this one (the inciter), too; it is, therefore, written "You shall feel no affection for him."
