Sirach 5:1-7

1 Set thy heart upon thy goods; and say not, I have enough for my life.
2 Follow not thine own mind and thy strength, to walk in the ways of thy heart:
3 And say not, Who shall control me for my works? for the Lord will surely revenge thy pride.
4 Say not, I have sinned, and what harm hath happened unto me? for the Lord is longsuffering, he will in no wise let thee go.
5 Concerning propitiation, be not without fear to add sin unto sin:
6 And say not His mercy is great; he will be pacified for the multitude of my sins: for mercy and wrath come from him, and his indignation resteth upon sinners.
7 Make no tarrying to turn to the Lord, and put not off from day to day: for suddenly shall the wrath of the Lord come forth, and in thy security thou shalt be destroyed, and perish in the day of vengeance.
