Rashbam
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.
Ibn Ezra
in her virginity Certain nouns in the Holy Tongue are never singular, like “juvenility” [Isaiah 54:6], “old age” [Genesis 37:3], “childhood” [cf . Isaiah 54:4], and “virginity” (likewise, certain nouns are never plural, like “young children” [Esther 3:13], “shoulders” [Genesis 9:23], “gold” [Genesis 24:22], and “iron” [Numbers 35:16]).
Ramban
WITH A STONE OR ‘B’EGROF’ (WITH HIS FIST). Judging from certain expressions of the Rabbis, egrof is the hand closed tightly, with the fingers gathered into the palm for the purpose of striking someone with it. Thus they speak of ba’alei egrofin [literally: “men of fists,” or men of power];124Kiddushin 76b. “egrofo (the fist) of Ben Abtiach.”125Keilim 17:12. A giant who lived in the time of the Second Sanctuary. Similarly ‘b’egrof’ of wickedness126Isaiah 58:4. means the hand of wickedness that strikes. Scripture thus mentioned two kinds of hitting — the hard one, with a stone, and the lighter one, with the fist, which in most cases does not cause death — in order to declare that in both cases an estimate [of the power of the stone or the fist with which he struck him] is needed, and the assailant is meanwhile imprisoned. If the assailed person dies, such as where he struck him a mortal blow, he is a murderer; he shall surely be put to death,127Numbers 35:16. but if he does not die, the assailant has to pay him for the loss of his labor and for the cost of the healing.
In the Mechilta [we find the following text]:128Mechilta here on the Verse. “Rabbi Nathan says: He has likened the stone to the fist and the fist to the stone. Just as the stone can cause death, so also the blow of the fist must be such that it is capable of causing death. And just as the fist is something that can be identified [and measured for the power of its blow], so also the stone must be such as can be identified. But if the stone with which he struck him became mixed up with other stones, the assailant is free.” This means if the stone became mixed up with other stones, they [e.i., the judges] estimate the lightest one and if it is incapable of causing death, they free the assailant.
Other scholars129Ibn Ezra and R’dak (in Sefer Hashorashim, root goraf). have said that the word egrof means “a clod of earth,” the term being derived from the expression: the grains shrivel under ‘megr’fotheihem’ (their clods of earth),130Joel 1:17. and the letter alef [in the word egrof is redundant], as is the alef in the word ezro’a [“arm,” where the word is really zro’a]. And this is the opinion of Onkelos who translated b’egrof — b’churmeiza (a piece of white stone or glazed tile). He mentioned these things also in order to tell us that the assailant who hits him with a clod of earth is also liable to be put to death, if he struck him on a sensitive spot where it is capable of causing death. This is to distinguish the law of the sword from the stone and egrof, for no estimate [of a sword or weapon] needs to be taken [since even a minute piece of metal — such as a needle — can also cause death], as the Sages have mentioned.131Sanhedrin 76b.

Rashi
וגם בעליו יומת AND HIS OWNER ALSO SHALL BE PUT TO DEATH by a visitation of God. You might perhaps think he shall be punished by human agency (the judges)! Scripture, however, states, (Numbers 35:21) “he that smote him (a human being) shall surely be put to death; for he is a murderer” — the force of these last words is to intimate that for a murder committed by himself you shall put him to death (i. e. he suffers death by human agency as is the law regarding a murderer), but you shall not put him to death on account of a murder committed by his ox; this must be left to God (Sanhedrin 15b; cf. also Mekhilta).
