Deuteronomy 12:30-32

Young's Literal Translation

³⁰ take heed to thee, lest thou be snared after them, after their being destroyed out of thy presence, and lest thou enquire about their gods, saying, How do these nations serve their gods, and I do so -- even I?

³¹ `Thou dost not do so to Jehovah thy God; for every abomination of Jehovah which He is hating they have done to their gods, for even their sons and their daughters they burn with fire to their gods.

³² The whole thing which I am commanding you -- it ye observe to do; thou dost not add unto it, nor diminish from it.
