χωρίζω

Matthew 19:6 χωριζέτω.¶ should separate.

So they are no longer two, but one flesh. Therefore what God has joined together, let man not separate.”

Here: A third-person command, 'let him not separate' or 'no one is to separate'. In marriage settings this was the ordinary Greek word for divorce, so Jesus is answering the divorce question he was asked in v.3.

Mark 10:9 χωριζέτω.¶ should separate.

Therefore what God has joined together, let man not separate.”

Acts 1:4 χωρίζεσθαι, to depart,

And while they were gathered together, He commanded them: “Do not leave Jerusalem, but wait for the gift the Father promised, which you have heard Me discuss.

Here: Present tense, middle voice: 'not to take yourselves away'. Here it means leaving the city. For Galileans the obvious move would have been to go home after the festival, so the order goes against what they would naturally do.

Acts 18:1 χωρισθεὶς having departed

After this, Paul left Athens and went to Corinth.

Acts 18:2 χωρίζεσθαι to depart

There he found a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife Priscilla because Claudius had ordered all the Jews to leave Rome. Paul went to visit them,

Here: 'To take themselves off, to depart.' Luke has just used the same verb for Paul leaving Athens (18:1). Paul has separated himself from Athens; the Jews have been made to separate themselves from Rome.

Romans 8:35 χωρίσει will separate

Who shall separate us from the love of Christ? Shall trouble or distress or persecution or famine or nakedness or danger or sword?

Here: Future tense: "will separate". The picture is of something coming between two parties and pulling them apart. The same verb ends the argument in v. 39: "nothing... will be able to separate us".

Romans 8:39 χωρίσαι to separate

neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.

Here: "To separate", meaning to put space between and cut off. It repeats the question of 8:35, "Who will separate us from the love of Christ?" Elsewhere the word was used for separation in marriage (Matt 19:6; 1 Cor 7:10–15), so it can carry the sense of a broken relationship.

1 Corinthians 7:10 χωρισθῆναι· is to be separated;

To the married I give this command (not I, but the Lord): A wife must not separate from her husband.

Here: Aorist passive infinitive. In Koine Greek this passive form often just means "to leave" or "go away" (Acts 18:1–2). Applied to marriage, it was everyday language for divorce, which in that world was carried out simply by one spouse leaving.

1 Corinthians 7:11 χωρισθῇ, she shall be separated,

But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.

1 Corinthians 7:15 χωρίζεται, χωριζέσθω· separates himself,, he should separate himself;

But if the unbeliever leaves, let him go. The believing brother or sister is not bound in such cases. God has called you to live in peace.

Here: Present tense, middle voice: "separates himself", "takes himself off". The unbeliever does it on their own initiative. In Greek and Roman life, walking out of a marriage like this was itself the divorce.

Philemon 1:15 ἐχωρίσθη he was separated [from you]

For perhaps this is why he was separated from you for a while, so that you might have him back for good—

Hebrews 7:26 κεχωρισμένος separated

Such a high priest truly befits us—One who is holy, innocent, undefiled, set apart from sinners, and exalted above the heavens.

Here: A perfect participle: a separation that happened and remains in effect. It probably refers both to his sinlessness and to the fact that he has now been removed from the realm of sinners into heaven (see the next phrase).
