A richly layered Greek verb whose root meaning is 'to bring together,' but whose New Testament uses span physical union, intellectual instruction, logical proof, and inferential reasoning. Paul uses it theologically to describe the body of Christ being 'knit together' in love (Col 2:2; Eph 4:16), echoing the physical sense of ligaments joining bones. Yet the same word can mean to instruct someone by 'putting things together' for them (1 Cor 2:16, quoting Isa 40:13 LXX), to prove a case by marshaling evidence (Acts 9:22), or to draw a conclusion from a vision (Acts 16:10). Spanish distinguishes these deftly: 'siendo-unido' for the bodily union, 'instruirá' for teaching, 'demostrando' for proving, and 'concluyendo' for inferring — four different words where Greek uses one.
