Prostasso is used for issuing instructions and for things or times set in advance.

The attested use most often concerns an instruction directed to someone, including directions about silence, priestly presentation, baptism, and Joseph's action. Perfect passive participles also describe things ordered by the Lord and appointed times.

1. Issuing a directive to someone · dominant

   The aorist active form occurs where a person gives specific directions: in Luke 5:14, Mark 1:44, and Matthew 8:4 the APB renders instructions not to tell anyone and to show oneself to the priest; in Acts 10:48 it renders an instruction to be baptized. In Matthew 1:24, the APB renders Joseph's action as doing what the angel of the Lord had ordered him.

2. Matters set or appointed beforehand · occasional

   The perfect passive participles describe items already set: in Acts 10:33 the APB renders “all the things having been ordered to you by the Lord.” In Acts 17:26, the APB renders the surrounding clause as God having determined “their appointed times and the boundaries of their dwelling place.”

   Acts 10:33Acts 17:26

In the Anselm Project Bible: Across the active occurrences, the APB commonly uses “ordered” and then states the requested action. For the perfect passive participles it uses “having been ordered” and describes “appointed times”; These renderings indicate the clauses' presentation rather than fixed English equivalents.
