Setting out an account or instruction · dominant
The middle indicative forms mark explanatory activity: in Acts 11:4 Peter begins an ordered account; in Acts 18:26 two people give a more accurate explanation of the way of God; and in Acts 28:23 the speaker’s extended presentation is joined with testimony and persuasion from morning until evening. In Acts 11:4 the APB renders the clause “Peter then began to explain it to them in order,” and in Acts 28:23 it renders “he explained the matter.”

Being exposed · occasional
In Acts 7:21, the aorist passive participle describes the condition preceding Pharaoh’s daughter’s rescue and upbringing of the child. The APB renders the clause “When he was exposed.”
In the Anselm Project Bible: The APB presents the three explanatory contexts with “explain” or “explained,” while Acts 7:21 has “was exposed.” These renderings confirm the clauses’ overall presentation rather than establish a precise English equivalent in every instance.
