Acts 2:14

Πέτρος σὺν τοῖς ἕνδεκα. The Twelve naturally take the leading place among the disciples, and Peter, who is usually the spokesman in the Gospels, begins the general address now, directing it principally to those who were dwellers in Jerusalem and the neighbouring country, for it was more likely to be these who gave vent to the mocking speeches than the foreigners who would better recognize the astounding nature of what had come to pass.

ἀπεφθέγξατο, spake forth unto them. The word is the same that is used to describe the gift which they had just received. ‘They spake as the Spirit gave them utterance,’ lit. ‘to speak forth’ (Acts 2:4). St Paul employs it when Festus had said he was mad. ‘I speak forth the words of truth and soberness’ (Acts 26:25).

ἐνωτίσασθε. The word signifies ‘to take anything into the ears.’ It is only found here in N.T. but is very common in the LXX., especially in the Psalms. Cf. also Genesis 4:23 (Lamech’s address); Job 32:10; Job 34:16; Job 37:13.
