Verse 23 is similar to verse 6, where Potiphar had no worries about the running of his household because he fully trusted Joseph. The reason the jailer need not concern himself is because the LORD was with Joseph. We may begin verse 23 with the reason clause: “Since the LORD was helping Joseph, the jailer did not worry about anything that Joseph was in charge of” or “Whatever Joseph undertook the LORD made it work out well.”
