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].
