Sirach 3: 17 - 18, 20, 28 - 29
17 My son, perform your tasks in meekness; then you will be loved by those whom God accepts.
18 The greater you are, the more you must humble yourself; so you will find favor in the sight of the Lord.
20 For great is the might of the Lord; he is glorified by the humble.
28 The affliction of the proud has no healing, for a plant of wickedness has taken root in him.
29 The mind of the intelligent man will ponder a parable, and an attentive ear is the wise man's desire.
