Proverbs 11:17
A kind man [from the Hebrew idea of covenant mercy and steadfast love; compassion expressed in action rather than sentiment; a disposition that treats others with patience, dignity, and generosity] benefits himself [literally “does good to his own soul”; kindness strengthens the inner life of a man; mercy produces relational stability, spiritual clarity, and personal peace], but a cruel man [harsh, violent, ruthless; a man who disregards the impact of his words and actions on others; one who uses force, intimidation, or harshness rather than wisdom] brings trouble [distress, chaos, and hardship; the natural consequences that flow from destructive character and behavior] on himself 
[cruelty is ultimately self-destructive; harshness damages relationships, isolates the heart, and returns consequences to the one who practices it].

Proverbs 11:24-25
11:24 One man gives freely [literally “scatters”], yet gains even more [many rewards of giving are intangible]; another [the stingy] withholds unduly, but comes to poverty.

11:25 A generous man will prosper; he who refreshes others [we should use our wealth to help others] will himself be refreshed.

Proverbs 11:28
11:28 Whoever trusts [cf. 1 Tim. 6:10] in his riches will fall [cf. Luke 16:19-31 re: the rich man and Lazarus], but the righteous will thrive like a green leaf [cf. Ps. 1:3].
