Proverbs 4

In verse 24 the writer challenges us to clean up our speech. He offers words of godly wisdom as an appropriate substitute for those words that are devious and perverse. I wonder if this passage is what Paul had in mind when he wrote in the Ephesian letter; "Do not let any unwholesome talk come out of your mouth, but only what is helpful for building others up according to their needs." (Eph 4:29)
