29 The appearance of Elijah would mean that the end time had come. According to 2 Kgs 2:11, Elijah was still alive. In Mal 4:5 it is said that Elijah would be the precursor of Messiah.
30 The phrase had risen could be understood to mean “had been resurrected,” but this is only a possible option, not a necessary one, since the phrase could merely mean that a figure had appeared on the scene who mirrored an earlier historical figure. The three options of vv. 7–8 will be repeated in v. 19.
