Matthew Henry and continuators on Proverbs 18:3

3 When the wicked cometh, then cometh also contempt, and with ignominy reproach.

This may include a double sense:—1. That wicked people are scornful people, and put contempt upon others. When the wicked comes into any company, comes into the schools of wisdom or into the assemblies for religious worship, then comes contempt of God, of his people and ministers, and of every thing that is said and done. You can expect no other from those that are profane than that they will be scoffers; they will be an ignominy and reproach; they will flout and jeer every thing that is serious and grave. But let not wise and good men regard it, for the proverb of the ancients says, such wickedness proceeds from the wicked. 2. That wicked people are shameful people, and bring contempt upon themselves, for God has said that those who despise him shall be lightly esteemed. As soon as ever sin entered shame followed it, and sinners make themselves despicable. Nor do they only draw contempt upon themselves, but they bring ignominy and reproach upon their families, their friends, their ministers, and all that are in any way related to them. Those therefore who would secure their honour must retain their virtue.
