Voyez notre pain: nous l’avions emporté frais de nos demeures, quand nous sommes partis pour aller chez vous; et maintenant le voilà tout rassis, piqué de moisissure.
Bartenura
ואם טמאים היו – the unconsecrated produce and the First Tithe into which pure heave-offering fell, for now, he is not able to produce Terumah of the tithe on another place, he separates upon it Terumah of the Tithe and sells them to Kohanim, and the Kohanim can eat them in small bits, in explanation, in a dry condition, like (Joshua 9:12 – not quoted correctly by Bartenura): “[This bread of ours….and see] how dry and crumbly it has become.”
Rashi
מה נצטדק How shall we justify ourselves? — This is a verbal form of צדק. In the same way every root whose first letter is צ when used in the Hithpael or Nithpael takes a ט instead of the ת of the prefix. This, however, is not placed before the first radical letter, but between the first two letters of the root. For example: נצטדק of the root צדק; (Daniel 4:13) “and let it be wet (ויצטבע)” of the root צבע to steep; Joshua 9:4) “and made as if they had been ambassadors (ויצטירו)”, of the same root as ציר in (Proverbs 13:17), ציר אמונים a faithful ambassador”; (Joshua 9:12) “we took our provision (הצטידנו)” of the same root as צדה in (Genesis 45:21) צדה לדרך “provision for the way”. And in the same way, with a root whose first letter is ס or ש, when it is used in the Hithpael, the ת of the prefix separate (i.e. is placed between) the first two letters of the root. For example: (Ecclesiastes 12:5) “and the grasshopper shall drag itself along heavily (ויסתבל)” from the root סבל “to carry a load”; (Daniel 7:8) “I considered (משתכל הוית) the horns”, from the root שכל to reflect on: (Micah 6:16) “for the statutes of Omri are kept (ישתמרו)” from the root שמר to keep; (Isaiah 59:15) “And he that departeth from evil (משתולל) is regarded as a fool”, from the same root as שולל in (Job 12:17) “He leadeth counsellors away (שולל) as though they were fools”; (Exodus 9:17) “Thou treadest down (מסתולל) my people”, from the same root as סלולה in (Jeremiah 18:15) “a way not trodden down (סלולה).”
Rashbam
מסתולל, the reflexive mode of the verb סלל as in סולו סולו דרך הרימו מכשול, “pave, pave a way and remove every obstacle, etc.,” (Isaiah 62,10). Just as the stones are pressed together to remove them as obstacles, so Pharaoh squeezed the Israelites so that they could not offer any resistance. Compare also Jeremiah 34,11 ויכבשום לעבדים ולשפחות, they “compressed” them into becoming male and female slaves. Concerning the grammatical principles underlying the use of the reflexive conjugation mitpael, every time this conjugation appears it has the letter ת preceding the first root letter, except the ones that have that letter at the end instead of at the beginning. Examples of the former are Psalms 94,4 יתאמרו כל פעלי און Words such as יתברך, יתגדל or in Ezekiel 38,23 והתגדלתי והתקדשתי, or Jeremiah 9,23 יתהלל המתהלל, or מתפלל in Exodus 10,2. The author lists a few more examples, showing that all of the letters of the aleph bet except the 7 letters ד'זט ס'ץ ש'ת, follow this pattern. When the first root letter is either a ש or a ת, the letter ת is appended at the end instead of at the beginning. The exception is a word whose root begins with the letter ס. One such example is our verse, the root being סל. The basic meaning is parallel to Numbers 16,13 תסתרר עלינו, where the word תסתורר is derived from the root שר. In examples such as ישתבח, ישתמר or משתכר, all of which have roots beginning with the letter ש, the letter ת signaling the conjugation התפעל is deferred until after the first root letter. In roots commencing with the letter ז or צ, no such letter ת signaling the reflexive conjugation appears at all. Instead, after the letter צ the letter ט is added to show us that we deal with the reflexive conjugation. Well known examples of these constructions are found in Genesis 44,16 נצטדק from the root צדק, and Joshua 9,12 הצטיידנו from the root ציד, provisions. Concerning the words with the first root letter ז, the letter signaling the reflexive conjugation is a ד, as in Daniel 2,9 הזדמנתון. The letters ד-ט-ת, by themselves when they appear at the beginning of the word, do not get an additional letter to indicate that the construction in which they appear is a reflexive conjugation. A prominent example of this is Numbers 7,89 וישמע את הקול מדבר, where the Torah did not write מתדבר. Another such example is Leviticus 21,4 לא יטמא בעל בעמיו, where because the root טמא begins with the letter ט the Torah did not write יתטמא, although the verb is in the reflexive mode, of course. The same is true in Samuel II 22,27 where the word תתפל in the line ועם עקש תתפל, does not have another letter ת at the beginning in order to signal that the verb is in the reflexive mode. [The author illustrated his point with still more examples, but I think he made his point adequately with the examples I have cited. Ed.]
Rashi
from shaking His flesh was agitated from the shaking, that it was shaken [by the suffering of] his illness. This word [רֻטֲפַש] has no similarity in Scripture, and according to the context, we found it necessary to explain according to the meaning of the topic. But the one who interprets it as an expression of mire (רפש) and claims that the “teth” is added to it, as in (Gen. 44:16), “How can we clear ourselves (נצטדק)?” is in great error, because the “teth” is added to a word only in the reflexive voice, and to a word in which there is a radical “zaddi,” but nor in other words. for example, צדק and נצטדק, and like (Lev. 13:44) צרוּע, stricken with “zaraath,” and נצטרע, was stricken with “zaraath.” (Prov. 25: 13), “an emissary (ציר) faithful,” and (Josh. 9:4), “and they went and disguised as ambassadors (ויצטירו)”; (Gen. 45:21) “צֵדָה, provision,” and (Josh. 9:12) “הִצְטַיַדְנוּ, we took... for our provision.”
