'Knocking' in the Bible

W I sleep, but my heart is awake.A sound! My love is knocking!M Open to me, my sister, my darling,my dove, my perfect one.For my head is drenched with dew,my hair with droplets of the night.

“Keep asking, and it will be given to you. Keep searching, and you will find. Keep knocking, and the door will be opened to you.

“So I say to you, keep asking, and it will be given to you. Keep searching, and you will find. Keep knocking, and the door will be opened to you.

Peter, however, kept on knocking, and when they opened the door and saw him, they were astounded.
