Gen 38:11

וַיֹּ֣אמֶר יְהוּדָה֩ לְתָמָ֨ר כַּלָּת֜וֹ שְׁבִ֧י אַלְמָנָ֣ה בֵית־אָבִ֗יךְ עַד־יִגְדַּל֙ שֵׁלָ֣ה בְנִ֔י כִּ֣י אָמַ֔ר פֶּן־יָמ֥וּת גַּם־ה֖וּא כְּאֶחָ֑יו וַתֵּ֣לֶךְ תָּמָ֔ר וַתֵּ֖שֶׁב בֵּ֥ית אָבִֽיהָ׃

Then Judah said to his daughter-in-law Tamar, “Live as a widow in your father’s house until my son Shelah grows up.” For he thought, “He may die too, like his brothers.” So Tamar went to live in her father’s house.
