Sirach 5:8LXX

6And say not: The mercy of the Lord is great, he will have mercy on the multitude of my sins.

7For mercy and wrath quickly come from him, and his wrath looketh upon sinners.

8Delay not to be converted to the Lord, and defer it not from day to day.

9For his wrath shall come on a sudden, and in the time of vengeance he will destroy thee.

10Be not anxious for goods unjustly gotten: for they shall not profit thee in the day of calamity and revenge.
