Pardon my ignorance. How do I explain what "countenance" is to my 5 and 7-year-olds? We are studying Genesis and came to Genesis 4:5 and my 7-year-old asked what is "countenance?" What does that mean? How do I explain? Honestly, I don't know myself.
"Countenance" is the expression on a person's face: happy, sad, angry, afraid, etc.
When Cain's countenance fell, it means he started frowning. The sides of his mouth went down.
