κλείω

Matthew 6:6 κλείσας having shut

But when you pray, go into your inner room, shut your door, and pray to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.

Here: "Having shut": the door is closed before the prayer begins. The verb can also mean to lock or bar. It shuts out the human audience completely.

Matthew 23:13 κλείετε you shut up

Woe to you, scribes and Pharisees, you hypocrites! You shut the kingdom of heaven in men’s faces. You yourselves do not enter, nor will you let in those who wish to enter.

Here: A present tense, so this is something they keep doing. The picture is a doorkeeper locking a door. The word also recalls the 'keys of the kingdom' in 16:19.

Matthew 25:10 ἐκλείσθη was shut

But while they were on their way to buy it, the bridegroom arrived. Those who were ready went in with him to the wedding banquet, and the door was shut.

Here: Passive, a single completed act; no one is named as doing it. Kleiō is the ordinary word for shutting or barring a door (Matt 6:6; Luke 11:7; Rev 3:7 'shuts and no one opens'). Here it means the entry is closed for good, as v. 12 confirms.

Luke 4:25 ἐκλείσθη was shut up

But I tell you truthfully that there were many widows in Israel in the time of Elijah, when the sky was shut for three and a half years and great famine swept over all the land.

Here: Passive: "was shut", implying God was the one who shut it (compare Deut 11:17). The picture is a door locked on the rain.

Luke 11:7 κέκλεισται, has been shut,

And suppose the one inside answers, ‘Do not bother me. My door is already shut, and my children and I are in bed. I cannot get up to give you anything.’

John 20:19 κεκλεισμένων shut

It was the first day of the week, and that very evening, while the disciples were together with the doors locked for fear of the Jews, Jesus came and stood among them. “Peace be with you!” He said to them.

Here: Literally "having been shut." The Greek tense (perfect) presents the doors as already shut and staying shut. Given the fear, bolting or barring is the natural picture.

John 20:26 κεκλεισμένων shut

Eight days later, His disciples were once again inside with the doors locked, and Thomas was with them. Jesus came and stood among them and said, “Peace be with you.”

Here: Perfect passive participle: the doors had been shut and stayed shut. The word covers both closing and barring or locking, and 'locked' fits the fearful setting of 20:19.

Acts 5:23 κεκλεισμένον shut

“We found the jail securely locked, with the guards posted at the doors; but when we opened them, we found no one inside.”

Acts 21:30 ἐκλείσθησαν were shut

The whole city was stirred up, and the people rushed together. They seized Paul and dragged him out of the temple, and at once the gates were shut.

1 John 3:17 κλείσῃ he may close up

If anyone with earthly possessions sees his brother in need, but withholds his compassion from him, how can the love of God abide in him?

Here: 'Shuts.' The word is used of doors and gates. Unlike the two present-tense verbs before it, this one presents a single, decisive act: he closes himself off.

Revelation 3:7 κλείσει κλείων will shut, shutting

To the angel of the church in Philadelphia write: These are the words of the One who is holy and true, who holds the key of David. What He opens no one can shut, and what He shuts no one can open.

Here: The future tense makes it a guarantee: what he has opened no one will ever shut.

Revelation 3:8 κλεῖσαι to shut

I know your deeds. Behold, I have placed before you an open door, which no one can shut. I know that you have only a little strength, yet you have kept My word and have not denied My name.

Here: To shut or lock. It is the same verb as in v.7 and Isaiah 22:22, and it is related to 'key' (kleis).

Revelation 11:6 κλεῖσαι to shut

These witnesses have power to shut the sky so that no rain will fall during the days of their prophecy, and power to turn the waters into blood and to strike the earth with every kind of plague as often as they wish.

Here: To shut the sky as you would lock a door or close a storehouse. The picture is the sky as a vault with openings that let the rain out (compare Gen 7:11; Deut 28:12).

Revelation 20:3 ἔκλεισεν shut

And he threw him into the Abyss, shut it, and sealed it over him, so that he could not deceive the nations until the thousand years were complete. After that, he must be released for a brief period of time.

Here: He shut (or locked) the Abyss. In the critical text the verb has no object: the entrance itself is shut. The angel has 'the key of the Abyss' (20:1), and in Revelation the one who holds the key decides who goes in and out (1:18; 3:7).

Revelation 21:25 κλεισθῶσιν may be shut

Its gates will never be shut at the end of the day, because there will be no night there.

Here: 'May be shut.' Passive: no one will shut them. The verb is used for barring city gates and doors (cf. Rev 3:7–8, 'an open door that no one can shut').
