"And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise." Deut. 6:6,7. This is the way it should be done. And how wonderful of the Lord to show us even in His animal kingdom. May this be the desire of our hearts as well.
