Proverbs 23:9 Speak not in the ears of a fool: for he will despise the wisdom of thy words.
10 Remove not the old landmark; and enter not into the fields of the fatherless:
11 For their redeemer is mighty; he shall plead their cause with thee.
This starts off telling us that when we try to talk to a person who is determined not to listen to the wisdom of God we are wasting our time . Anything we say they will not pay attention to it and will probably not care to speak to you again.Again we see that God is telling not to defraud someone or take something that is not ours .God will fight for those that are mistreated. This winds up letting us know that our redeemer is mighty and He will defend us to the ends of the earth. He will especially defend those that have no one else to defend them. Let us ever be mindful of those that are in need and be ready to help in any possible.
