וַיְהִ֗י הֵ֚ם מְרִיקִ֣ים שַׂקֵּיהֶ֔ם וְהִנֵּה־אִ֥ישׁ צְרוֹר־כַּסְפּ֖וֹ בְּשַׂקּ֑וֹ וַיִּרְא֞וּ אֶת־צְרֹר֧וֹת כַּסְפֵּיהֶ֛ם הֵ֥מָּה וַאֲבִיהֶ֖ם וַיִּירָֽאוּ׃
At nangyari, habang inaalisan nila ng laman ang kanilang mga sako, narito, nasa sako ng bawat isa ang kanyang supot ng pera. At nang makita nila at ng kanilang ama ang kanilang mga supot ng pera, sila ay natakot.
Rashbam
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.
Radak
בשקו, in the actual text it does not say בפי שקו, as we already mentioned on verse 27.
