Found more than seventy times in the New Testament, the Greek verb “anoigo” meant “open” or “be open.”
This term first occurs in Mt. 2:11 (the treasure brought for Jesus was “opened”). In Mt. 3:16 this word is used to say the heavens were “opened” to Jesus after He was baptized. Jesus “opened” His mouth and then presented the Sermon on the Mount (Mt. 5:2). This word is also used in conjunction with things like a door (Acts 5:19) and the human eye (Mt. 9:30).
John made great use of this term in the book of Revelation (Rev. 3:7-8, 20; 4:1; 5:2-5, 9; 6:1, 3, 5, 7, 9, 12; 8:1; 9:2; 10:2, 8; 11:19; 12:16; 13:6; 15:5; 19:11; 20:12).
