Acts 27:9 tn Or “unsafe” (BDAG 383 s.v. ἐπισφαλής). The term is a NT hapax legomenon.
Acts 27:9 sn The fast refers to the Jewish Day of Atonement, Yom Kippur. It was now into October and the dangerous winter winds would soon occur (Suetonius, Life of Claudius 18; Josephus, J. W. 1.14.2-3 [1.279-281]).
Acts 27:9 tn The accusative articular infinitive παρεληλυθέναι (parelēluthenai) after the preposition διά (dia) is causal. BDAG 776 s.v. παρέρχομαι 2 has “διὰ τὸ τὴν νηστείαν ἤδη παρεληλυθέναι because the fast was already over Ac 27:9.”
Acts 27:9 tn Grk “Paul advised, saying to them.” The participle λέγων (legōn) is redundant in English and has not been translated. On the term translated “advised,” see BDAG 764 s.v. παραινέω, which usually refers to recommendations.sn Paul advised them. A literary theme surfaces here: Though Paul is under arrest, he will be the one to guide them all through the dangers of the storm and shipwreck, showing clearly God’s presence and protection of him. The story is told in great detail. This literary effect of slowing down the passage of time and narrating with many details serves to add a sense of drama to the events described.
