Sirach assumes the parental tone again. He warns that we should test ourselves in this life. We should recognize what is bad for us and not give in to it. Not everything is good for everybody. Do not be greedy for delicacies! You have to use restraint. Overeating can lead to illness. Gluttony can lead to stomach aches or even to death. If you guard against over eating, you will prolong your life.
Sirach uses his parental tone in reminding others about the sting of sin. If you have sinned, stop! Ask forgiveness! You should run away from sin like you would run away from a snake. Do not go near to sin or it will bite you like a snake. Sin has lion’s teeth that can destroy people. Breaking the law is like a sharp two edged sword because there is no healing the wounds that it inflicts. Stay away from sin or you will get hurt.
