Sirach 32:14LXX

12In many things be as if thou wert ignorant, and hear in silence and withal seeking.

13In the company of great men bake not upon thee: and when the ancients are present, speak not much.

14Before a storm goeth lightning: and before shamefacedness goeth favour: and for thy reverence good grace shall come to thee.

15And at the time of rising be not slack: but be first to run home to thy house, and there withdraw thyself, and there take thy pastime.

16And do what thou hast a mind, but not in sin or proud speech.
