אִשָּׁ֣ה תְאָרֵ֗שׂ וְאִ֤ישׁ אַחֵר֙ ישגלנה [יִשְׁכָּבֶ֔נָּה] בַּ֥יִת תִּבְנֶ֖ה וְלֹא־תֵשֵׁ֣ב בּ֑וֹ כֶּ֥רֶם תִּטַּ֖ע וְלֹ֥א תְחַלְּלֶּֽנּוּ׃
Thou shalt betroth a wife, and another man shall lie with her; thou shalt build a house, and thou shalt not dwell therein; thou shalt plant a vineyard, and shalt not use the fruit thereof.
Tosefta Megillah
One who leads the responsive recitation of the Shema, or blesses over fruit or over matzah, behold, he should not answer "amen" after himself. If he answered ["amen" after his own prayer], behold, this is how ignoramuses act. We do not answer with either an "orphaned amen" (i.e., where one does not know to what blessing he is saying "amen"), or a "truncated [amen]" (i.e., where one does not pronounce the entire word). Ben Azzai says, one who answers with an "orphaned amen" -- his children will be orphaned; with a "truncated [amen]," his days will be truncated. But whoever prolongs [his amen], his days and years will be prolonged.
