The fifth command tells how we should act toward our parents, guardians, or others to whom we owe respect. We are to do what our parents ask us to do while we live under their care. Even when parents ask us to do things we feel are not right, we should still submit to their authority. When we leave home to marry or live independent lives we are then free of their authority. Yet even then we are to care for our parents, particularly when they are old and weak.
Murder is caused by hatred which is the result of anger and jealousy.
These in their turn often arise from simple things such as hurt pride. The chances are none of us will ever commit murder, but we will hate. So God asks us to try to accept others, particularly those who are different or who have trod on our toes. Adultery is sexual intercourse with someone other than a marriage partner. God's intention is that we make love with only one person in our lives.
