44 “You’ve lost your mind!” Such a response to the miraculous is not unusual in Luke-Acts. See Luke 24:11; Acts 26:25. The term μαίνομαι (mainomai) can have the idea of being “raving mad” or “totally irrational” ( ). It is a strong expression.
45 Grk “she kept insisting that the situation was thus” (cf. ἔχω 10.a). Most translations supply a less awkward English phrase like “it was so”; the force of her insistence, however, is that “it was Peter,” which was the point under dispute.
46 The two imperfect tense verbs, διϊσχυρίζετο (diischurizeto) and ἔλεγον (elegon), are both taken iteratively. The picture is thus virtually a shouting match between Rhoda and the rest of the believers.
47 The assumption made by those inside, “It is his angel,” seems to allude to the idea of an attending angel (cf. Gen 48:16 ; Matt 18:10; Test. Jacob 1:10).
