Proverbs 11:25; Proverbs 21:13; Proverbs 28:10

25 The generous man will be prosperous, And he who waters will himself be watered.
13 He who shuts his ear to the cry of the poor Will also cry himself and not be answered.
10 He who leads the upright astray in an evil way Will himself fall into his own pit, But the blameless will inherit good.
