Agkura denotes an anchor cast from a vessel and, once, the image used for hope's secure firmness.

The attested use is chiefly of anchors handled from a vessel—thrown out, proposed as a pretense, or cast off into the sea; Hebrews 6:19 uses the singular term in describing hope as secure and firm.

1. Vessel anchors in maritime action · dominant

   In Acts 27:29, the accusative plural occurs where the APB renders sailors throwing four anchors from the stern; Acts 27:30 places the plural in their stated pretense of stretching out anchors from the bow. In Acts 27:40, the same plural is present as the APB renders the anchors being cast off and let go into the sea.

2. Image for hope's security · rare

   In Hebrews 6:19, the accusative singular occurs in the statement that hope is secure and firm; the APB renders the clause "We have this hope as an anchor of the soul" and continues with entry behind the curtain.

   Hebrews 6:19

In the Anselm Project Bible: The APB explicitly uses "anchors" in the vessel scenes and "an anchor of the soul" in Hebrews 6:19. These renderings confirm the clauses' presentation rather than establish every lexical nuance.
