TT points to Bava Metzia 59a (R. Chelbo): a man must always be careful about the honor of his wife, for blessing is found in a man’s house only on account of his wife.
English of Core Text: R. Chelbo said: a person must always be careful about the honor of his wife, for blessing is found in a man’s house only on account of his wife, as it is said “And he dealt well with Avram for her sake.”
On the daf / in context: Although the verse’s immediate subject is Pharaoh, the Gemara reads the benefit that came to Avram as mediated through Sarai, establishing the principle that household blessing travels through the wife’s merit.
