James 3:13-18-
13 ¶ Who among you is wise and understanding? By his good conduct he should show that his works are done in the gentleness that comes from wisdom.
14 But if you have bitter envy and selfish ambition in your heart, don’t boast and deny the truth.
15 Such wisdom does not come down from above but is earthly, unspiritual, demonic.
16 For where there is envy and selfish ambition, there is disorder and every evil practice.
17 But the wisdom from above is first pure, then peace-loving, gentle, compliant, full of mercy and good fruits, unwavering, without pretense.
18 And the fruit of righteousness is sown in peace by those who cultivate peace.

Cultivating peace. Just as our gardens require cultivation and care, so does peace. Other words to describe the act of cultivating: trying to acquire, pursuing, fostering, encouraging, nurturing, working hard at, or trying to develop.

1 Peter 3:10-11-
“For the one who wants to love life and to see good days, let him keep his tongue from evil and his lips from speaking deceit,
11 ¶ and let him turn away from evil and do what is good. Let him seek peace and pursue it…”

Proverbs 12:20-
“Deceit is in the hearts of those who plot evil, but those who promote peace have joy.”
