Mishnah Arachin 5:2: [If one said,] “the worth of my hand is upon me,” they estimate his worth with his hand and [what it would be] without his hand. In this respect vows of worth are more stringent than vows of value, [while] there is an aspect of vows of value that is more stringent than vows of worth How so? If one said, “my value is upon me” and then he dies, his heirs must give it. [But if he said,] “my worth is upon me,” and then he dies, his heirs need not give anything because dead persons have no worth. [If he said,] “the value of my hand or foot is upon me,” he has said nothing; [but if he said,] “the value of my head is upon me,” he must give his whole value. This is the general rule: Anything upon which his life depends, he must give his whole value.

דמי ידי עלי. שמין אותו כמה הוא שוה ביד. וכמה הוא שוה בלא יד. זה חומר בנדרים מבערכין. וחומר בערכין מבנדרים. כיצד. האומר ערכי עלי ומת. יתנו היורשין. דמי עלי ומת. לא יתנו היורשים. שאין דמים למתים. ערך ידי וערך רגלי עלי לא אמר כלום. ערך ראשי וערך כבדי עלי נותן ערך כולו. זה הכלל. דבר שהנשמה תלויה בו נותן ערך כולו:

Mishnah Arachin 5:3: [If one said:] “Half my value is upon me,” he must give half his evaluation. [But if he said,] “The value of one half of me he is upon me,” he must give his full value. [If he said] “Half of my worth is upon me,” he must give half his worth. [If he said,] “The worth of half of me is upon me,” he must give his whole worth. This is the general rule: Anything on which his life depends, he must give his whole worth.

חצי ערכי עלי נותן חצי ערכו. ערך חציי עלי נותן ערך כולו. חצי דמי עלי נותן חצי דמיו. דמי חציי עלי נותן דמי כולו. זה הכלל דבר שהנשמה תלויה בו נותן ערך כולו:
