Proverbs 19:26 (ESV) “He who does violence to his father and chases away his mother is a son who brings shame and reproach”
God does not give frivolous or optional commands. Each one is equally important and breaking any one of them is a serious offense. Therefore, the command not to murder is as important as the one that forbids adultery. In the ten, one may seem somewhat less important to the casual reader. Exodus 20:12 says “Honor your father and your mother, that your days may be long in the land that the Lord your God is giving you.”
There are good reasons why this command should be given careful attention. One is that all authority comes from God and is delegated by God (Romans 13:1). If you reject His delegated authority, you are rejecting the King. God gives us parents to love us, train us, guide us, discipline us and to prepare us for life. If we reject their roles and authority, we are rebelling against God’s order and rule.
To go one step further and mistreat your mother or father is a very dangerous rebellious offense. This can include neglecting your parents in their old age or refusing to help them in times of distress or illness. Don’t chase away your parents.
