'Opens' in the Bible

“Write to the angel of the church in Philadelphia:“The Holy One, the True One, the One who has the key of David, who opens and no one will close, and closes and no one opens says:

Listen! I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and have dinner with him, and he with Me.

One of the elders said to me, "Don't weep. Behold, the Lion who is of the tribe of Judah, the Root of David, has overcome; he who opens the book and its seven seals."
