Bible Warns Against Secret Societies

Deu 13:6  If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;
Deu 13:7  Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth;
Deu 13:8  Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him:
Deu 13:9  But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.
