'Peaceable' in the Bible

for kings and all who are in [positions of] high authority, so that we may live a peaceful and quiet life in all godliness and dignity.

not addicted to wine, not a bully nor quick-tempered and hot-headed, but gentle and considerate, free from the love of money [not greedy for wealth and its inherent power—financially ethical].

For the time being no discipline brings joy, but seems sad and painful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness [right standing with God and a lifestyle and attitude that seeks conformity to God’s will and purpose].
