Ibn Ezra
He that killeth an ox, etc. I look to him that trembleth at my word, not to those that sacrifice burnt offerings, and at the same time act badly; for he that killeth an ox, מכה איש is as guilty as if he slew a man; it is considered as murder on his part, because the offering is not brought properly; or is guilty as if he struck a man, not killing, but hurting and wounding him;2Comp. והכה איש את רעהו וגו׳, and one smite another with a stone, or with his fist, and he die not. Ex. 21:18.
Ibn Ezra
אגרף Some hard thing to strike with.5A. V., First. In this sense it is used in Rabbinical literature. Comp. בעלי אגרפין men with force (Pesachim 53); compare besides באגרף (Ex. 21:18).6In his commentary on Ex. 21:18, I. E. mentions this comparison in the name of Saadiah, while the other explanation, introduced here by the words, Others render it, is given, in his abridged commentary on Ex. 21:18, as his own, introduced by the word ויתכן, It is also right to say. Others7Very probably R. Jonah is meant, whose explanation is quoted in the commentary of I. E. on Ex. 21:18; he derived the word from the root גרף to sweep. render it a piece of hard earth, and connect it with מגרפותיהם their clods (Joel 1:17).

Rashi
for the judgment of the Lord and for quarrels It is appropriate to use the term “judgment” (לְמִשְׁפַּט) concerning money matters, an example being (Num. 27:11) “and it shall be for the Children of Israel as a legal norm (לְחֻקַּת מִשְׁפָּט).” “And for quarrels” (וְלָרִיב) refers to capital cases and bodily injuries, an example being (Exod. 21:18) “And if men quarrel, etc.” (יְרִיבוּן).
Rashi
אשר ימות בה signifies: which has a size sufficient to cause death, as the Targum understands it. Because it has been stated, (Exodus 21:18) “If one man smote another with a stone” but it assigned no size for it, one might think that it means, whatever size it may be! Therefore it states here, “by which one may die” (Sifrei Bamidbar 160:3).
