The Torah (the first five books of the Bible) was given to Moses on Mount Sinai and was completed sometime in the 14th century BC. It is likely that the Torah’s rabbis and the Jewish religious community developed the laws of kashrut. The laws of kashrut are discussed in the Torah but not codified, and they are not mentioned again in the Torah until the end of the second book, the book of Deuteronomy. It is speculated that the laws of kashrut were codified sometime in the first century BC. There are many rules in the Torah and Talmud about what foods can be consumed and which cannot. This is because, according to Biblical law, food is considered pure when it has been made ritually pure by the Jewish law of kashrut.
