מוֹצָ֥א שְׂפָתֶ֖יךָ תִּשְׁמֹ֣ר וְעָשִׂ֑יתָ כַּאֲשֶׁ֨ר נָדַ֜רְתָּ לַיהוָ֤ה אֱלֹהֶ֙יךָ֙ נְדָבָ֔ה אֲשֶׁ֥ר דִּבַּ֖רְתָּ בְּפִֽיךָ׃ (ס)
Wyrzeczenia ust twoich przestrzegaj, i spełniaj jakoś ślubował Wiekuistemu, Bogu twojemu, dobrowolnie, coś wypowiedział usty twojemi.
Mishnah Megillah
There is no difference between one who is prohibited by vow from benefiting from his fellow and one who is prohibited by vow from [benefiting from] his food, except in the matter of setting foot [on his property] and of vessels which are not used for [preparing] food. There is no difference between vowed offerings and freewill-offerings except that he is responsible for vowed offering but not responsible for freewill-offerings.
Mishnah Terumot
He who intends saying ‘terumah’ and says ‘tithe’, or ‘tithe’ and says ‘terumah’; ‘Burnt-offering’ and he says ‘peace-offering’, or ‘peace-offering’ and he says ‘burnt-offering’; ‘[I vow] that I will not enter this house,’ and says ‘that house’, ‘That I will not derive any benefit from this [man],’ and says ‘from that [man],’ he has said nothing until his heart and mind are at one.
