G1516–εἰρηνικός–eirēnikos

All chastening seems for the present to be not joyous but grievous; yet afterward it yields the peaceful fruit of righteousness to those who have been exercised thereby.

εἰρηνικὸν eirēnikon “peaceable”

But the wisdom that is from above is first pure, then peaceful, gentle, reasonable, full of mercy and good fruits, without partiality, and without hypocrisy.

εἰρηνική, eirēnikē “peaceable,”
