Comentario citado sobre Deuteronómio 4:42

לא תרצח. Wherever the term רציחה appears it refers to killing without adequate justification. A deliberate murderer is to be executed as we know from Numbers 35,16-16. Similar verses in Kings I 21,19 when King Achav had framed someone resulting in judicial murder is also included in this definition of לא תרצח, [though he could have claimed that Naval, the victim, could have been found innocent by the judges. Ed.] When the terms הריגה, or מיתה are used to describe killing this means that there was no excuse for the killer to commit his act. (compare Kayin slaying his brother in Genesis 4,8) On the other hand, in Leviticus 20,16 where the Torah decrees והרגת את האשה, this refers to judicial killing for cause. Concerning the use of the word רוצח, murderer, in Deuteronomy 4,42 as applicable to someone who killed inadvertently, the reason why the Torah used this term there was only because in the same context deliberate murder was also discussed. This is my answer to the heretics who have admitted to me that the Latin translation of the Bible describing רציחה “killing,” without distinction as to the reason for the killing, is sloppy, most inaccurate. They were so careless in spit of the fact that in their “own” books such as Deuteronomy 32,39 we have the line אני אמית ואחיה, “it is I Who kill and resurrect,” showing that the Torah uses different expressions describing different kinds of killing.

THEN MOSES SEPARATED THREE CITIES. Rabbi Abraham ibn Ezra explained it to mean: “on the day that Moses separated three cities [to function as cities of refuge], he then said the words of the covenant [as stated in the following section].” But it is not correct. Rather, it is to be understood in its simple sense. Moses had gathered all Israel to explain to them the Torah and he began with words of reproof; after he uttered in their presence his words of reproof concerning what they had done, the admonishments about idolatry and the Unity of G-d, and completed [his statement] to them with the charge that they observe His statutes and His commandments so that it may be well with them — then he said in their presence before them: “Now we shall fulfill the commandment that G-d has commanded us, and Bezer in the wilderness, Ramoth in Gilead, and Golan in Bashan will be cities of refuge that every manslayer that kills any person through error may flee thither.”¹¹⁷See Verses 42-43. And although they would not legally provide refuge until [the cities of refuge] in the land of Canaan [on the western side of the Jordan] were set apart, Moses said, “‘If a commandment has come to our hands we shall fulfill it,’¹¹⁸Makkoth 10 a. so that it may be well with us.” Afterwards he called with a great voice to all Israel that were there and said to them, Hear, O Israel, the statutes and the ordinances etc.,¹¹⁹Further, 5:1. for now he commenced to speak of the commandments and the explanation of the Torah, as I have explained at the beginning of the section These are the words.¹²⁰Above, 1:1.
