The house where Paul lodged in Corinth 'adjoined' the synagogue, a geographical detail with narrative import—proximity to the Jewish assembly even after Paul's break with it. The verb denotes spatial contiguity, used rarely in the NT but common in geographical descriptions. Spanish 'contigua' and French 'confiner' preserve the boundary-touching sense, highlighting how Paul's Gentile mission remained physically adjacent to Jewish centers, symbolizing the gospel's continuity with Israel.
