I spent two years in a private school run by Baptists and we did do rote memorization of certain verses but we read the Bible through many times over the course of those two years so things with Biblical connotation just jump right out when you encounter them, it might not be word for word but you recognize it. I hated it then, and have issues to this day with certain types of Baptist, but it’s done right for me in life. There’s something else going on with the murder of this poor boy.
You want your kids to grow up knowledgeable about Scripture, but you don't want then to hate it by associating Bible memory with punishment.
God's prescription of teaching Scripture....
Deuteronomy 6:4-9“Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might. 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. You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. You shall write them on the doorposts of your house and on your gates.
