Rabbi Moshe Ben Maimon (1135 – 1204) known as the Rambam and Maimonides, while being a revolutionary in so many disciplines, in medicine, philosophy, astronomy, and one of the greatest codifiers of Jewish law, he was firmly grounded in the Bible and tradition, traced back to the Moses who led the Israelites out of Egypt and the one who brought the world the Ten Commandments.

Maimonides in Egypt was the personal physician for the court of the Saladin, and was requested to come and serve Richard the Lionheart who was in Israel at the time, which he refused. Maimonides is also famously known for his Guide for the Perplexed.

The following, are some of the great words of advice as penned by Maimonides himself. Maimonides promised and assured all those who would follow in this way, they would live happy, healthy, blessed, and long (er) lives.

PEOPLE ARE NOT AT LIBERTY TO RISK AND/OR JEOPARDIZE
THEIR LIVES OR THEIR HEALTH.

Our Sages forbade many matters because they involve a threat to life. Whenever a person transgresses these guidelines, saying: "I will risk my life, what does this matter to others," or "I am not careful about these things," he should be punished by stripes for rebelliousness.

They include: A person should not place his mouth over a conduit through which water flows and drink. Nor should he drink at night from rivers and lakes, lest he swallow a leech without seeing.

Similarly, a person should not drink water that was left uncovered, lest a snake or other poisonous crawling animal might have drunk from them, and as a result, the person would die.
A PERSON IS COMMANDED NOT TO EVEN GIVE THE APPEARANCE – OF BEING IN A POSITION OR SITUATION OF A COMPROMISING AND DISHONEST NATURE. EVEN IF THEY ACTUALLY DID NOT DO ANYTHING WRONG.

If a Plaintiff tells a person: "Come and stand together with the witness. You do not have to testify, but the borrower will become frightened and panic, thinking that you are two witnesses (and judgment is decided based on the testimony of two witnesses.) and he will admit the debt on his own volition," the student is forbidden to stand and make it appear that he is a witness even though he does not deliver testimony.

With regard to this and similar matter, Exodus 23:7 states: "Keep distant from words of falsehood."

A PERSON’S ACTUAL AND LEGAL PLACE OF LIFE ANCHORING AND ATTACHMENT DEPENDS MORE ON WHERE THEIR MIND IS, THAN WHERE THEY FIND THEMSELVES PHYSICALLY.

When students sleep in the house of study, but go and eat their Sabbath meals [in the homes of] people who live in the fields and the vineyards, who show hospitality to wayfarers passing through, [the house of study is considered their "Sabbath place"] and not the place where they eat.

They may walk (the limit allowed on Sabbath) two thousand cubits from the house of study in all directions. [The rationale is] that were it possible for them to eat in the house of study, ( although normally the two thousand cubits is measured from where the person is eating their Shabbat meals, in this case) they would not go to the fields at all (their real minds are always only on the house of study). They consider the house of study alone as their dwelling. The measurement of the two thousand cubits must be from where they have their main focus on.

IN THE EYES OF G OD IT IS WORSE TO STEAL FROM ANOTHER PERSON THAN ACT AGAINST GO D.

The punishment for the person who uses false measures is greater than the punishment for licentious sexual behavior, for this is a sin between a person and his colleague, and this is a sin between a person and G od.

Whoever denies the commandment of just measures is considered as if he denied the exodus from Egypt, (this person doesn’t rely or believe in the miraculous abilities of Go d) which is the first of God's commandments.

Conversely, one who accepts the mitzvah (commandment and good deed) of just measures is considered as if he acknowledges the exodus from Egypt (and the possibility for a just and kind Go d to always, ultimately come through for those who put their faith in Him), which brought about all of God's commandments.

It is a positive commandment to correct the scales, weights and measures carefully and to be exact in their measure when making them, as Leviticus 1 9:36 states: "You shall have correct scales...."

Similarly, with regard to the measurement of land, one must be exact according to the principles of geometry. Even a fingerbreadth of land (that is unlawfully kept when sold) is considered to be a great loss, as if it were filled with saffron.
