Hupostasis denotes settled assurance in hope, boasting, and perseverance, and can identify what is reproduced of someone.

The attested usage chiefly concerns settled assurance: it frames boasting, preparedness, hope, and continued firmness. In Hebrews 1:3, it occurs in a clause describing the reproduction of what belongs to him.

1. Settled assurance or firm basis · dominant

   In 2 Corinthians 9:4 the dative form occurs in the warning that unpreparedness could bring shame, and the APB renders the closing phrase with “this confidence.” In 2 Corinthians 11:17 it stands in a statement about boasting, while Hebrews 11:1 and Hebrews 3:14 place the noun in clauses about hope and holding firm to the end; the APB renders these contexts with “confidence.”

2. What is reproduced of someone · rare

   In Hebrews 1:3, the genitive form occurs in the description of one who is the radiance of glory and bears all things; the APB renders the relevant clause “the reproduction of his essence.”

   Hebrews 1:3

In the Anselm Project Bible: The APB presents the term as “confidence” in the passages concerning boasting, hope, and perseverance, and as “essence” within “the reproduction of his essence” in Hebrews 1:3. These renderings identify the verse-level presentation rather than a fixed English equivalent.
