Rambam - Book of Knowledge - Laws of Idolatry - Chapter 6

This is the first book of the Mishneh Torah of the Rambam, Rabbi Moshe ben Maimon. Laws of Torah Study.
This chapter explains the laws of one who serves the Ov and Idoni and what they are. It covers one who passes his son through the Molech and what the Molech is. It addresses whether he passed but did not, or vice versa. It also covers whether part of his descendants passed, whether his descendants were valid or invalid, and whether he was asleep or blind. It explains what a monument (Matzeiva) or carved stone (Even Maskit) is, what carved stones in the Temple are, and what one plants a tree beside the Altar.
