The bulk of Acts 3 is Peter’s second sermon in the Book of Acts. The first one was after the miracle of Pentecost, and now this second one comes after the miracle of the healed man at the temple. Significantly, Luke shares this sermon as the healed man still holds on to him. Luke uses words of continuous action: the healed man walked and kept walking, leaped and kept leaping, praised God, and kept praising God. Now, we see in this text that he held on to the apostles and kept holding on to them. Some translations say he clung, which captures the emotive language of the original better. The healed man clung and kept clinging to the apostles.
Luke tells us in the introduction to this miracle that the early Christians devoted themselves to the apostles' teachings (Acts 2:42). Now, in Acts 3:11, the healed man's action of clinging to the apostles provides a specific example of how one within the church devotes himself to the apostles. He literally clung to them.
