Genesis 35:4

And - ear-rings which were in their ears - Whether these rings were in the ears of the gods, or in those of Jacob's family, we may rest assured that they were not mere ornaments, but served for superstitious purposes. Ear-rings were certainly worn as amulets and charms, first consecrated to some god, or formed under some constellation, on which magical characters and images were drawn. A very ancient and beautiful one of this kind brought from Egypt, cut out of a solid piece of cornelian, now lies before me. It was evidently intended for the ear, as the opening is too small for any human finger; and it is engraved all over with strange characters and images, which prove that it was intended for a talisman or amulet. It seems to be such a one as St. Augustine describes, Epist. 73, which was suspended from the tip of the ears both of men and women, not for the purpose of ornament, but through an execrable superstition, for the service of demons. "Execranda superstitio ligaturarum, in quibus etiam inaures virorum in summis ex una parte auriculis suspensae deputantur, non ad placendum hominibus, sed ad serviendum daemonibus." See Clarke on Genesis 24:22 (note).

35:4 And they gave to Jacob - His servants, and even the retainers to his family, gave him all the strange gods, and the ear - rings they wore either as charms, or to the honour of their gods. Jacob took care to bury their images, we may suppose, in some place unknown to them, that they might not afterwards find and return to them.
