From the time he made him overseer … blessed the Egyptian’s house for Joseph’s sake: some translations repeat the words that were expressed in Gen 39.4. However, see Good News Translation. Blessed in this context has the sense of doing good to someone, and in particular to make them prosper. If the more general term for blessed is not suitable here, we may say, for example, “The LORD made everything in Potiphar’s house turn out well.” Bible en français courant has a rendering that may serve as a model: “From that time, because of Joseph, the Lord made the affairs of the Egyptian prosper. That prosperity extended to all his goods, both in his house and in his fields.”
