How we cite our quotes: (Chapter:Verse)
Quote #4
The righteous know the needs of their animals, but the mercy of the wicked is cruel. (NRSV 12:10)
A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel. (KJV 12:10)
This is an ancient pro-animal-rights statement. The "mercy of the wicked is cruel" means that what the wicked consider "mercy" is really just more cruelty.
Quote #5
A soft answer turns away wrath, but a harsh word stirs up anger. (NRSV 15:1)
A soft answer turneth away wrath: but grievous words stir up anger. (KJV 15:1)
Stirring the pot is both immoral and counter-productive here. Speaking gently to an angry person helps diffuse their temper—but harsh words are just going to spur anger onwards.
Quote #6
The one who lives alone is self-indulgent, showing contempt for all who have sound judgment. (NRSV 18:1)
Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom. (KJV 18:1)
Proverbs wants people to be participating in their family and their communities—that's where the righteous life and the wise life play out. Keeping to one's self prevents that from happening. Proverbs considers it to be like hoarding up your life just for yourself.
