Acts 17:20 New English Translation

²⁰For you are bringing some surprising things^[a] to our ears, so we want to know what they^[b] mean.”

Acts 17:20 tn BDAG 684 s.v. ξενίζω 2 translates the substantival participle ξενίζοντα (xenizonta) as “astonishing things Ac 17:20.”
Acts 17:20 tn Grk “these things,” but since the referent (“surprising things”) is so close, the repetition of “these things” sounds redundant in English, so the pronoun “they” was substituted in the translation.
