"The Bible Lesson In all that men have written, where can be found anything that has such a hold upon the heart, anything so well adapted to awaken the interest of the little ones, as the stories of the Bible? In these simple stories may be made plain the great principles of the law of God. Thus by illustrations best suited to the child's comprehension, parents and teachers may begin very early to fulfill the Lord's injunction concerning His precepts: “Thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in the thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.” Deuteronomy 6:7 .

"And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up."
Ellen White directly references Deuteronomy 6:7 in this passage.
