God hates the worship of idols and that is one sin that is always cause for bringing a city down or to get cursed in the Bible. It is a pretty serious sin and it gets mentioned right off the bat in the ten commandments. Here is a list of idol names, customs, incidents and speech surrounding idols and their worship by men and women
1) The first instance of idols in the Bible can be seen in Laban’s family. When Jacob with his family decides to depart from Laban without his knowledge, Rachel, Laban’s daughter steals her father’s idols. When Laban chases after Jacob and catches up with him and lays the charge that he has stolen his gods(plural), Jacob denies this and says that whomsoever was found with Laban’s gods will be put to death. Laban searches everywhere but could not find the images as Rachel had hidden them with her camel’s furniture. She tells her father that she cannot come down from her camel to greet him because she has her period!!! So Laban searches everywhere but ends up not finding the images.
Genesis 31:17-35 (KJV)
 Then Jacob rose up, and set his sons and his wives upon camels;  And he carried away all his cattle, and all his goods which he had gotten, the cattle of his getting, which he had gotten in Padan-aram, for to go to Isaac his father in the land of Canaan.  And Laban went to shear his sheep: and Rachel had stolen the images that were her father’s.  And Jacob stole away unawares to Laban the Syrian, in that he told him not that he fled.  So he fled with all that he had; and he rose up, and passed over the river, and set his face toward the mount Gilead.  And it was told Laban on the third day that Jacob was fled.  And he took his brethren with him, and pursued after him seven days’ journey; and they overtook him in the mount Gilead.  And God came to Laban the Syrian in a dream by night, and said unto him, Take heed that thou speak not to Jacob either good or bad.  Then Laban overtook Jacob. Now Jacob had pitched his tent in the mount: and Laban with his brethren pitched in the mount of Gilead.  And Laban said to Jacob, What hast thou done, that thou hast stolen away unawares to me, and carried away my daughters, as captives taken with the sword?  Wherefore didst thou flee away secretly, and steal away from me; and didst not tell me, that I might have sent thee away with mirth, and with songs, with tabret, and with harp?  And hast not suffered me to kiss my sons and my daughters? thou hast now done foolishly in so doing.  It is in the power of my hand to do you hurt: but the God of your father spake unto me yesternight, saying, Take thou heed that thou speak not to Jacob either good or bad.  And now, though thou wouldest needs be gone, because thou sore longedst after thy father’s house, yet wherefore hast thou stolen my gods?  And Jacob answered and said to Laban, Because I was afraid: for I said, Peradventure thou wouldest take by force thy daughters from me.  With whomsoever thou findest thy gods, let him not live: before our brethren discern thou what is thine with me, and take it to thee. For Jacob knew not that Rachel had stolen them.  And Laban went into Jacob’s tent, and into Leah’s tent, and into the two maidservants’ tents; but he found them not. Then went he out of Leah’s tent, and entered into Rachel’s tent.  Now Rachel had taken the images, and put them in the camel’s furniture, and sat upon them. And Laban searched all the tent, but found them not.  And she said to her father, Let it not displease my lord that I cannot rise up before thee; for the custom of women is upon me. And he searched, but found not the images.
2) God tells Jacob to make Him an altar in Bethel. Jacob tells his household to put away all the strange gods that were among them. From this we can infer that idols were being worshiped in Jacob’s house and most probably these were the idols that Rachel stole from her father. Everyone obeys Jacob’s word, they give him all their strange gods and the earrings which were in their ears and Jacob hides these under an oak tree. Why were the earrings surrendered, was wearing earrings a practice commonly followed by idol worshipers or was that in response to Jacob’s command to be clean?
Genesis 35:1-4 (KJV)
 And God said unto Jacob, Arise, go up to Beth-el, and dwell there: and make there an altar unto God, that appeared unto thee when thou fleddest from the face of Esau thy brother.  Then Jacob said unto his household, and to all that were with him, Put away the strange gods that are among you, and be clean, and change your garments:  And let us arise, and go up to Beth-el; and I will make there an altar unto God, who answered me in the day of my distress, and was with me in the way which I went.  And they gave unto Jacob all the strange gods which were in their hand, and all their earrings which were in their ears; and Jacob hid them under the oak which was by Shechem.
