Targum for Genesis 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 said Judah to Tamar his daughter-in-law: ‘Remain a widow in thy father’s house, till Shelah my son be grown up’; for he said: ‘Lest he also die, like his brethren.’ And Tamar went and dwelt in her father’s house.
