Sirach 18:25LXX

23Before prayer prepare thy soul: and be not as a man that tempteth God.

24Remember the wrath that shall be at the last day, and the time of repaying when he shall turn away his face.

25Remember poverty is the time of abundance, and the necessities of poverty in the day of riches.

26From the morning until the evening the time shall be changed, and all these are swift in the eyes of God.

27A wise man will fear in every thing, and in the days of sins will beware of sloth.
