2 John
API: GET /api/v1/proofs?passage=2+John+1:1ff
Every paragraph, question and clause whose proofs cite 2 John: 7 passages, each as it is cited, with what cites it, linked to its proof. A passage cited whole and in part is listed for each, side by side (as Romans 8:28 and 8:28–30 are); the API’s answer for a passage finds both.
