וַתַּנַּ֥ח בִּגְד֖וֹ אֶצְלָ֑הּ עַד־בּ֥וֹא אֲדֹנָ֖יו אֶל־בֵּיתֽוֹ׃
And she laid up his garment by her, until his master came home.
Rashi on Genesis
אדניו HIS MASTER — Joseph’s master (not the master or owner of the garment).
וַתַּנַּ֥ח בִּגְד֖וֹ אֶצְלָ֑הּ עַד־בּ֥וֹא אֲדֹנָ֖יו אֶל־בֵּיתֽוֹ׃
And she laid up his garment by her, until his master came home.
