And he said unto them, Set your hearts unto all the words which I testify among you this day, which ye shall command your children to observe to do, all the words of this law.
And these words, which I command thee this day, shall be upon thy heart,
Therefore, ye shall lay up these my words in your heart and in your soul and bind them for a sign upon your hand that they may be as frontlets between your eyes.
1 Chronicles 22:19
Now set your heart and your soul to seek the LORD your God; arise therefore and build the sanctuary of the LORD God, to bring the ark of the covenant of the LORD and the holy vessels of God into the house that is to be built unto the name of the LORD.
My son, forget not my law, but let thine heart keep my commandments:
And the man said unto me, Son of man, behold with thine eyes and hear with thine ears and set thine heart upon all that I show thee for to the intent that I might show them unto thee art thou brought here: declare all that thou dost see to the house of Israel.
Let these words sink down into your ears, for the Son of man shall be delivered into the hands of men.
Therefore, it is necessary that we with more diligence keep the things which we have heard, so that we do not fall.
