"So they shall eat of the fruit of their own way and be satiated with their own devices"
Solomon wants to drive deep into the soul of his young students that you will create the world you live in. The way you treat people will be the basis of how you will be treated by the vast majority of people.
eat
This is the Hebrew word akal which means to eat. The idea here is you will live in and off of the kind of person that you are. If you are a mean spirited, selfish person, then you will live in and off of that kind of world where it is all dog-eat-dog and viciousness.
What many people don't realize is that how they treat people and how ethical they are is creating the world in which they live. They will find the kind of world they create for themselves.
fruit
This is the Hebrew word peri which means fruit, earnings, product. God's universe plays by God's rules: you reap what you sow. If you sow selfishness, then you reap selfishness. If you sow love others first, then you reap love in return.
Solomon is pointing out that those who think they are getting ahead by violence, selfishness, cheating, and predatory ways will eventually be surrounded by people who will do that to them. "According to his deeds" is a maxim in the biblical economy.
way
This is the Hebrew word derek which means way, road, path, journey. It is used metaphorically here for the lifestyle you lead. God says that there is an absolute correspondence between how you treat people and how selfish you are and the kind of opportunities and world you live in.
satiated
This is the Hebrew word sabea which means satiated or satisfied. The idea is that you will be filled up or full of. In this case you will be sick of people who are treating you exactly like you are treating others.
If it seems like everyone treats you like dirt, then it may be because you treat everyone else like dirt. If you notice the pride and ego in everyone, then it may be that you are proud and egotistical. The very schemes that you try on others will be done to you. That is why the Lord Jesus says "Do unto others as you would have done to you."
devices
This is the Hebrew word moetsah which means counsel, plan, principle, device. Solomon is saying how you treat people is how you will be treated. People tend to reflect back on others what they receive. Few people realize this and wonder why so many people are angry, proud, or heartless towards them. It is often because they are this way towards others.
Until tomorrow,
