פירוש על בראשית 42:35

צרור כספו means HIS BUNDLE OF MONEY.

כספיהם, seeing that the letter ס in the word כספיהם “swallows” the otherwise necessary chataf patach under it, the letter פ, normally weak, without the dagesh, has been given a dagesh in this instance. A similar example of this construction is found in the relationship of נסך, nessech, and נסכיהם, nisskeyhem.

בשקו, in the actual text it does not say בפי שקו, as we already mentioned on verse 27.
