נט הַמְשַׁחְרֵר שְׁנֵי עֲבָדִים בִּשְׁטָר אֶחָד, לֹא קָנוּ עַצְמָם. לְפִיכָךְ הַכּוֹתֵב כָּל נְכָסָיו לִשְׁנֵי עֲבָדָיו בִּשְׁטָר אֶחָד, אַף עַצְמָם לֹא קָנוּ. וְאִם כָּתַב בִּשְׁתֵּי שְׁטָרוֹת, קָנוּ וּמְשַׁחְרְרִין זֶה אֶת זֶה. בַּמֶּה דְּבָרִים אֲמוּרִים, כְּשֶׁכָּתַב בְּכָל שְׁטָר מִשְּׁנֵיהֶם: כָּל נְכָסַי נְתוּנִים לִפְלוֹנִי וּפְלוֹנִי עֲבָדַי,  אֲבָל אִם כָּתַב: חֲצִי נְכָסַי לִפְלוֹנִי עַבְדִּי, וַחֲצִי נְכָסַי לִפְלוֹנִי עַבְדִּי, אַף בִּשְׁנֵי שְׁטָרוֹת לֹא קָנוּ כְּלוּם.

One who liberated two slaves with one document,  they do not acquire their freedom. Therefore if a person writes a single legal document transferring all his property to two slaves, they do not acquire their freedom. If the master wrote two documents, one for each slave, they acquire their freedom.

When does the above apply? When the master wrote in each legal document: “All my property is given to so and so and so and so, my slaves.

If, however, he writes: “Half of my property is given to so and so, my slave, and the other half is given to so and so, my slave,” even if the owner wrote two documents, the slaves do not acquire anything.
