Torah, means "Instruction", "Teaching," or "Law". It is the compilation of the first five books of the Hebrew Bible, namely the books of BeReshit/Genesis, Shemot/Exodus, Vayikra/Leviticus, BaMidbar/Numbers, and Devarim/Deuteronomy. Christians know it as the Pentateuch and the Five Books of Moses or Torah in Judaism. The Torah is God’s law/teaching/instruction/guidance given to Moses on Mountain Sinai. Moses got the information from God Himself, and Moses, our teacher, put it together for us. The Torah is the Law and should not be broken ​​by anyone. Even Y-H-V-H God abides by it. For example, when God took Israel out of Egypt, they were in the desert, and God provided them with food in the form of manna. He provided for them Sunday through Friday, but not on Saturday. The Israelis got a double portion on Friday for Saturday. If you are going to learn any of the books in the Bible, let it be The Torah. Read it so much that you know it by heart. Only then can you not be deceived by any one person or religion of the world.

A word about the Septuagint: it does not exist anymore. It was destroyed. The original Septuagint was a translation of the first five books of the Tanakh, known as the Torah, or the Five Books of Moses, only, not the entirety of the Hebrew Bible. Septuagint means “seventy,” referring to the seventy-two Rabis translators—six from each tribe of Israel—involved in translating the Torah/Pentateuch from Hebrew to Greek in the third century BCE, by request of Ptolemy II Philadelphus (seventy-two is rounded down to seventy, hence the Roman numeral LXX). It was a translation that took place between 285 and 247 BCE. This Septuagint was lost and destroyed in the burning of the Library of Alexandria in the year 48 BC. No copies of it were made. The Septuagint that you can buy today is not a real Septuagint nor a translation made by Hebrew-speaking people. The modern "versions" are based on 4th-century CE copies (like Code Vaticanus) that reflect centuries of revisions, editorial changes by scholars like Origen, and Christian adaptations, making them distict from the original. However, it was named Septuagint nonetheless (kind of like calling any brand of cotton swabs Q-tips, which is a name brand of cotton swabs). The Hebrew people have kept the Torah and the rest of the Hebrew Bible unchanged since it was first made. It does not matter what the Hebrew Bible's publication is; they are all the same. That is one of God’s laws, that not even a word or a letter from His law should be changed (Deut. 4:2). The Hebrew Bible does not need any revisions or editorial changes. It is God’s word, His word is perfect.
