G1516–εἰρηνικός–eirēnikos

At the time all punishment seems to be pain and not joy: but after, those who have been trained by it get from it the peace-giving fruit of righteousness.

εἰρηνικὸν eirēnikon “peaceable”

But the wisdom which is from heaven is first holy, then gentle, readily giving way in argument, full of peace and mercy and good works, not doubting, not seeming other than it is.

εἰρηνική, eirēnikē “peaceable,”
