2אֲבָל הַחוֹלֶה שֶׁתָּשַׁשׁ כֹּחַ כָּל הַגּוּף. וְכָשַׁל כֹּחוֹ מֵחֲמַת הַחֹלִי עַד שֶׁאֵינוֹ יָכוֹל לְהַלֵּךְ עַל רַגְלוֹ בַּשּׁוּק וַהֲרֵי הוּא נוֹפֵל עַל הַמִּטָּה. הוּא [הַנִּקְרָא] שְׁכִיב מֵרַע. וּמִשְׁפְּטֵי מַתְּנוֹתָיו אֵינָם כְּמַתְּנַת בָּרִיא. כֵּיצַד. שְׁכִיב מֵרַע שֶׁצִּוָּה וְאָמַר לִתֵּן לִפְלוֹנִי כָּךְ וְכָךְ בֵּין בְּחל בֵּין בְּשַׁבָּת. בֵּין כָּתַב בֵּין לֹא כָּתַב. זָכוּ הַכּל כְּשֶׁיָּמוּת בְּכָל מַה שֶּׁנָּתַן לָהֶם וְאֵינוֹ צָרִיךְ קִנְיָן. שֶׁדִּבְרֵי שְׁכִיב מֵרַע כִּכְתוּבִין וְכִמְסוּרִין הֵן. וְדָבָר זֶה מִדִּבְרֵי סוֹפְרִים. וְאַף עַל פִּי שֶׁאֵינוֹ אֶלָּא מִדִּבְרֵיהֶם עָשׂוּ אוֹתָהּ כְּשֶׁל תּוֹרָה. כְּדֵי שֶׁלֹּא תִּטָּרֵף דַּעְתּוֹ עָלָיו כְּשֶׁיֵּדַע שֶׁאֵין דְּבָרָיו קַיָּמִים:
However, when a person becomes ill to the extent that he feels weak throughout his entire body - indeed, because of his illness, his strength has dwindled to the extent that he cannot walk on his feet in the market place, and he is confined to his bed - he is referred to as a sh'chiv me'ra. The laws applying to his gifts differ from those applying to the gifts given by a healthy person. What is implied? When a sh'chiv me'ra gives orders and says: "Give so and so such and such, and so and so such and such" the intended recipients acquire all the property apportioned to them when the sick person dies. This applies whether he issued his instructions during the week or on the Sabbath, and whether or not a written record was drawn up. Nor must his instructions be confirmed by a kinyan for the statements of a sh'chiv me'ra are considered as if they have been written down, and transferred. This is a Rabbinic decree. Nevertheless, although it is only a Rabbinic decree, our Sages conveyed upon this convention the power of Scriptural Law, so that a dying person will not become exasperated, knowing that his words are of no consequence.
