דַּבֵּר֙ אֶל־בְּנֵ֣י יִשְׂרָאֵ֔ל וְיִקְחוּ־לִ֖י תְּרוּמָ֑ה מֵאֵ֤ת כָּל־אִישׁ֙ אֲשֶׁ֣ר יִדְּבֶ֣נּוּ לִבּ֔וֹ תִּקְח֖וּ אֶת־תְּרוּמָתִֽי׃
“Katakanlah kepada bani Israel supaya mereka mengambil persembahan khusus bagi-Ku. Dari setiap orang yang hatinya tergerak untuk memberi dengan rela, kamu harus mengambil persembahan khusus-Ku.

...Look and see that it is not fitting to profane Shabbat with the work of the Tabernacle. For is it not that the Tabernacle and all of its vessels do not have holiness in them until the Tabernacle is established in its place and the Divine Presence rests upon it? It comes out that the making of the Tabernacle is only a preparation for something that will only be holy after its making. However, there is no need to say that Shabbat is intrinsically holy...

החרש והשוטה והקטן – All of them are derived from one Biblical verse, as it is written (Exodus 25:2): “Tell the Israelite people to bring Me gifts; [you shall accept for Me] from every person whose heart so moves him.” [The words] "אל בני ישראל" /”to the Israelite people” -except for a heathen; [the words] מאת כל איש/“from every person” – except for a minor; [the words] "אשר ידבנו לבו"/”whose heart so moves him” – except for a deaf-mute and imbecile, who lack the temperament to be able to donate. And a minor is not able [even] to do a little, from [the words] "אשר ידבנו לבו"/”whose heart so moves him,” for there is a minor who arrived at the season of taking vows, who has the temperament to be able to donate. [The words] "וזאת התרומה אשר תקחו מאתם"/”And these are the gifts that you shall accept from them” (verse 3), excluding to the person who donates what is not his. And the “imbecile”- who loses what they give him is called an imbecile/"שוטה".

Another reason for the word כל, all, may be similar to what I explained on Exodus 25,2 "from every man, etc." The word included orphans, minors, women, etc. Moses actually used two expressions of amplification, i.e. את כל. The reason Moses used only two amplifying statements here, namely את כל, and not a third one representing the wealthy (see page 756), is simple. There was no reason why the wealthy person would not come even if not especially invited seeing he would be happy to be part of the community.
