Deuteronomy 6: 6-7

2 Corinthians 1:3-(KJV) 3 Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; 4 Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. 5 For as the sufferings of Christ abound in us, so our consolation also aboundeth by Christ.
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.
