1: τέρας
(Strong's #5059 — Noun Neuter — teras — ter'-as )

"something strange," causing the beholder to marvel, is always used in the plural, always rendered "wonders," and generally follows semeia, "signs;" the opposite order occurs in Acts 2:22,43; 6:8 , RV; 7:36; in Acts 2:19 "wonders" occurs alone. A sign is intended to appeal to the understanding, a "wonder" appeals to the imagination, a power (dunamis) indicates its source as supernatural. "Wonders" are manifested as Divine operations in thirteen occurrences (9 times in Acts); three times they are ascribed to the work of Satan through human agents, Matthew 24:24; Mark 13:22; 2—Thessalonians 2:9 .

2: θάμβος
(Strong's #2285 — Noun — thambos — tham'-bos )

"amazement," is rendered "wonder" in Acts 3:10 . See AMAZE , A, No. 2.
