Midrash for Sanhedrin 122:11

אמר רבא מנא אמינא לה דכתיב (דברים יג, ח) מאלהי העמים אשר סביבותיכם הקרובים אליך וגו' מה לי קרובים ומה לי רחוקים הכי קא"ל מטיבותן של קרובים אתה למד מה טיבותן של רחוקים

Now, what does it matter whether they are far or near? — But the Writ means this: from the character of the near idols you can learn the nature of the distant ones.<span class="x" onmousemove="('comment',' A seducer generally seeks to entice one to worship distant idols by describing their great power, but avoids mention of the near ones, which his victims would themselves know to be powerless; therefore Scripture warns one against such enticement, by pointing out that the near (and known) idols are an object lesson for the distant ones. Scripture thus assumes that such blandishments were used. ');">¹⁰</span>
