to be at peace: to live in ongoing, harmonious relationship with other people.
This verb names a settled way of living together, not a single act. In the New Testament it is always a command to a group ("keep on being at peace"), pointing to the daily work of staying on good terms rather than to one moment of making up.
Its backdrop is the rich Old Testament idea of peace as wholeness and well-being, not merely the absence of a quarrel. So the call is warmer and fuller than "stop fighting": it is an invitation to the kind of thriving, unbroken community that God himself gives. Every time the word appears, a mention of the "God of peace" is close by, so the command is never bare advice but a summons to live out the peace God is and grants.
The reach of that peace widens by context. Most often it is peace inside the community, believers with one another. In one case it stretches as far as it possibly can: "as far as it depends on you, live at peace with everyone," enemies included, with the realistic admission that the other side may still refuse.
One thing this word does not do in the New Testament is describe forcing peace on someone or brokering a settlement between two parties. Ancient Greek could use it that way (the Roman Empire boasted of "pacifying" the seas), and the New Testament has other words for actively making peace (εἰρηνοποιέω) or reconciling estranged parties (καταλλάσσω). This word stays on the quieter side of the family: not imposing peace from above, but living at peace side by side.
Whether the original wording of 1 Thessalonians 5:13 is the reflexive "among yourselves" or the variant "with them," which decides whether the call to peace is church-wide or aimed at the relationship with the leaders named in the previous verse.

- minorityThe variant "with them": the command concerns the congregation's relationship with its leaders.
