So here’s a nagging question that I have had: Why is there not a label for a Ground-Inference-Ground arc? I might call it an Inverse Bilateral.
Psalm 86:8-10 seems like a perfect candidate. Because verse 10 is a restatement of verse 8, it does not seem accurate to arc 8-9 together, grounded by 10. Nor 9-10 together as an inference from 8.
