"God gave to Israel instruction in all the principles essential to physical as well as to moral health, and it was concerning these principles no less than concerning those of the moral law that He commanded them: MH 283.1"
"And said, If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee."
Exodus 15:26 directly links obedience to God's commands with physical health, which aligns with EGW's statement about God giving Israel instructions for both physical and moral health. This is more than just a thematic parallel; it's a direct principle illustrated in the verse.
"“These words, which I command thee this day, shall be in thine heart: 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. And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes. And thou shalt write them upon the posts of thy house, and on thy gates.” Deuteronomy 6:6-9 . MH 283.2"
"And these words, which I command thee this day, shall be in thine heart: 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. And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes. And thou shalt write them upon the posts of thy house, and on thy gates."
Ellen White directly references Deuteronomy 6:6-9 in this passage.
"Thou shalt be blessed above all people: there shall not be male or female barren among you, or among your cattle."
EGW directly quotes Deuteronomy 7:14.
