והפילו השופט, he will stretch him out on the post. [The lashes are not applied when the victim is standing upright, but when he is at least inclined. (Makkot 22) Ed.]

מכה רבה, more than the victim’s general constitution can bear.

ונקלה אחיך, if he were to be unable to control his bowel movements on account of his pain..

ויבמה, by doing so he removes her status as yevamah from her as she is now his wife. She will be a wife in all respects including the legislation applying to divorcing her and possibly remarrying her.

ולא ימחה שמו מישראל, in that the child born from this union will be considered by G’d as if the deceased had fulfilled the commandment to be fruitful. This is easily understood when we consider that this child is the product of a legal marriage entered into by the deceased husband of his mother. The fact that the deceased’s brother did not have to go through a marriage ceremony with the widow of his brother makes this clear to everyone. This explains why G’d would be angry at the brother who refuses to marry his sister-in-law, as he thereby deprived his deceased brother forever from fulfilling the mitzvah of being fruitful

ככה יעשה לאיש אשר לא יבנה את בית אחיו, he deserves this public embarrassment seeing he had refused to restore the house his deceased brother had begun to build when he betrothed his (now) widow. This reminds us of the statement in Shabbat 118 by Rabbi Yossi who did not refer to his wife as אשתי, “my wife,” but as ביתי, “my house.”

Ed.] Even though the Torah had not only given permission to the widow in the yevamah legislation to publicly embarrass her brother in law for failing to do his duty by marrying her, but had even commanded her to do so, in this instance, when a wife tries to save her husband’s life by resorting to tactics which embarrass his opponent she is punished for doing so.

לא יהיה לך בביתך איפה ואיפה, after having mentioned the ways in which the benevolent presence of the Shechinah can be assured for the Jewish people, the Torah reminds you that if G’d hates corrupt justice this is not an isolated instance of what G’d hates in interpersonal relations, something we call “civics,” He even hates it when someone owns and keeps instruments which are designed to be used in a corrupt, deceptive, manner, so that even without putting these instruments to use the owner/keeper has become guilty of violating a negative commandment. G’d’s presence, Shechinah, cannot tolerate neighbours who even think of using such means to deceive others.

תמחה את זכר עמלק, by killing even their livestock, as King Sha-ul was commanded in Samuel I 15,3. This was intended to avenge the unprovoked attack by Amalek against G’d when, by attacking His people, they demeaned His image, besmirched His honour.
