Tosefta for Nedarim 17:7

Rabbi Meir says, [regarding the verse,] "It is better not to vow, than to vow and not fulfill" (Ecc. 5:4), it is better than both of these that one not take a vow at all (Ned. 9a:7). Rabbi Yehuda says, it is better not to vow [than to vow and not fulfill], but is it not better than both of these to bring his lamb to the [Temple] courtyard and lean on it and slaughter it?
