All the blessing comes in the merit of the wife

All the blessing comes in the merit of the wife. And to Avraham he did good on her account. Regarding a person's blessing—one also needs to know a very great thing.
A man should know, that a man's entire blessing is from how he respects his wife, how he speaks to her.
He has blessing as reflected in the verse: "And to Avraham he did good on her account"—for the sake of Sarah. As our Sages say, "Honor your wives so that you may be enriched." Honor your wives, [and] you will be wealthy. This is one of the greatest things through which a person can become rich. By means of his respecting his wife.
There are two things. There is [one thing] "tithing so that you will be enriched. There is one [saying]: "Honor your wives so that you may be enriched." Honor your wives, [and] you will be wealthy. A person needs to do both.
