'Knock' in the Bible

'Ask, and it shall be given to you; seek, and ye shall find; knock, and it shall be opened to you;

and I say to you, Ask, and it shall be given to you; seek, and ye shall find; knock, and it shall be opened to you;

from the time the master of the house may have risen up, and may have shut the door, and ye may begin without to stand, and to knock at the door, saying, Lord, lord, open to us, and he answering shall say to you, I have not known you whence ye are,

lo, I have stood at the door, and I knock; if any one may hear my voice, and may open the door, I will come in unto him, and will sup with him, and he with me.
