ואברם כבד מאד, he was very wealthy both in herds and flocks, as well as in other possessions, all chattels. The attribute כבד for great wealth has been chosen since, seeing it consists of chattels, it is “weighty” in the truest sense of the words. Similar literary formulations are found in Isaiah 1,30 כאלה נובלת עליה, “as a terebinth wilted of its leaf,” the prophet uses the word עלה, leaf, as something descriptive of a small tree like the terebinth whose leaf patterns account for its character. Its leaves make it such an outstanding tree. Similarly, the expression קרועי בגדים. In Samuel II 13,31 “with their clothes rent,” or מגולחי זקן, “shorn of beard,” in Jeremiah 41,5. The adjectives used fit the noun they describe, so here too the adjective כבד “heavy,” fits such metals as silver and gold, so that wealth may be appropriately described in such terms. [The author explains why a simple term such as עשיר, “rich,” was not used instead of the adjective כבד, literally “heavy.” Ed.]

No, my lord: I am not drunk, as you think. Rather, "I am a woman of a troubled spirit" - my spirit is troubled about me, from my great distress. And the construct form (smikhut) [of, "a troubled spirit"] is like, "of fallen leaves" (Isaiah 1:30); "of shaven beards" (Jeremiah 41:5); of torn clothes" (II Samuel 13:31).

בהמלו בשר ערלתו, if we were to say that the word בהמלו is in a passive mode. We would have to ask how it could conclude with the pronoun ו which introduces an action by him on the flesh of his foreskin. We never find that a passive mode is followed immediately by an active mode. If, on the other hand, we are to understand the word בהמלו as standing on its own, without direct relationship to the words בשר ערלתו, or if the Torah had written בהמול בשר ערלתו without the pronoun ו, we would not have a problem with the text as it is before us. One could perhaps resolve the problem of the text that we have by saying that the expression בהמלו describes a condition Avraham experienced as a result of his foreskin having been circumcised. We encounter a similar construction in Isaiah 1,30 where the word נובלת describes the condition of leaves of the tree described, i.e. they are shriveled or have wilted. The word is an intransitive verb, and the terebinth referred to as the trunk to which these leaves belonged is certainly not subject to wilting or shriveling. One could argue similarly, that Avraham was now considered נמול, (verse 26) circumcised, seeing that the flesh of his foreskin had been removed. In a similar manner we can also understand the words קרועי בגדים in Samuel II 13,31. The clothes of the men (David's servants) were torn, not the men themselves. The same is true of Samuel II 15,32 where the word קרוע does not refer to Chushai but to his tunic which was torn. Jeremiah 41,5 has a similar construction, מגולחי describes the condition of these men after their beards had been shaved off.
Rashi
With torn garments. Because they heard blasphemies of the Name [of God].27See Maseches Sanhedrin 60a. One who hears another Jew blaspheme God must rend his clothing. Ravshokei's blasphemy was in comparing God to the pagan deities.—Radak Alternatively, they rend their clothing on account of the terrible news and threats that they just heard, an event similar to II Shmuel 13:31 and II Melochim 5:7.
