Knocking at a door or calling out
When desiring to enter a gate or door, it is respectful of the privacy of others knock or to call out before entering.
“Thus Moses commanded the holder of a pledge to stand without and call to the owner to come forth (Deuteronomy 24:10). This was to avoid the violent intrusion of cruel creditors.
Peter stood knocking at the outer door (Acts 12:13; 12:16), and the three men sent to Joppa by Cornelius made inquiry and ‘stood before the gate’ (Acts 10:17-18). The idea is that the guard over your privacy is to be placed at the entrance.”
And when he [Peter] knocked at the door of the gate, a servant-girl named Rhoda came to answer. —Acts 12:13 LSB
Knocking is mentioned in the Gospels of Matthew and Luke. Jesus Christ told His disciples,
“Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened.” —Matthew 7:7-8 LSB
‘Behold, I stand at the door and knock; if anyone hears My voice and opens the door, I will come in to him and will dine with him, and he with Me. —Revelation 3:20 LSB
Once the head of the house gets up and shuts the door, and you begin to stand outside and knock on the door, saying, ‘Lord, open up to us!’ then He will answer and say to you, ‘I do not know where you are from.’ —Luke 13:25 LSB
Speaking of the 2nd coming of Christ, Scripture tells Believers to,
“Be like men who are waiting for their master when he returns from the wedding feast, so that they may immediately open the door to him when he comes and knocks. —Luke 12:36 LSB
