written upon the heart
"For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people.
"This is the covenant that I will make with them after those days, says the LORD: I will put My laws into their hearts, and in their minds I will write them,"
My son, forget not my law; but let thine heart keep my commandments: 2 For length of days, and long life, and peace, shall they add to thee. 3 Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart: 4 So shalt thou find favour and good understanding in the sight of God and man. 5 Trust in the LORD with all thine heart; and lean not unto thine own understanding. 6 In all thy ways acknowledge Him, and He shall direct thy paths. 7 Be not wise in thine own eyes: fear the LORD, and depart from evil.
