The heart is more deceitful than any other thing, and it is also perverse. Who can uncover its secrets? I, the Lord, search the heart and probe the mind to reward all according to their conduct and as their deeds deserve.
My son, concentrate attentively on my words; pay heed to the instructions I pass on to you. Do not let them slip from your mind; keep them forever in your heart.
Hear, O Israel, the Lord, our God, is Lord alone. You shall love the Lord, your God, with all your heart, and with all your soul, and with all your might.
My son, do not forget my teaching, but cherish my commandments in your heart, for they will bring you length of days, more years of life, and an abundance of prosperity.
Even though I wander through the valley of the shadow of death, I will fear no evil, for you are at my side, with your rod and your staff that comfort me.
