“Only pay attention and watch yourselves closely so that you do not forget the things which your eyes have seen and they do not depart from your heart all the days of your life. Make them known to your children and your grandchildren [impressing these things on their mind and penetrating their heart with these truths]—

You approached and stood at the foot of the mountain, and the mountain burned with fire to the [very] heart of the heavens: darkness, cloud and thick gloom.

But from there you will seek the Lord your God, and you will find Him if you search for Him with all your heart and all your soul.

Therefore know and understand today, and take it to your heart, that the Lord is God in the heavens above and on the earth below; there is no other.

You shall love the Lord your God with all your heart and mind and with all your soul and with all your strength [your entire being].

And you shall remember [always] all the ways which the Lord your God has led you these forty years in the wilderness, so that He might humble you and test you, to know what was in your heart (mind), whether you would keep His commandments or not.

Otherwise, you may say in your heart, ‘My power and the strength of my hand made me this wealth.’

“Do not say in your heart when the Lord your God has driven them out before you, ‘Because of my righteousness the Lord has brought me in to possess this land,’ but because of the wickedness of these nations the Lord is dispossessing them before you.

“And now, Israel, what does the Lord your God require from you, but to fear [and worship] the Lord your God [with awe-filled reverence and profound respect], to walk [that is, to live each and every day] in all His ways and to love Him, and to serve the Lord your God with all your heart and with all your soul [your choices, your thoughts, your whole being],

“It shall come about, if you listen obediently and pay attention to My commandments which I command you today—to love the Lord your God and to serve Him with all your heart and with all your soul [your choices, your thoughts, your whole being]—

you shall not listen to the words of that prophet or that dreamer of dreams; for the Lord your God is testing you to know whether you love the Lord your God with all your heart and mind and all your soul [your entire being].

He shall not acquire multiple wives for himself, or else his heart will turn away [from God]; nor [for the same reason] shall he acquire great amounts of silver and gold.

so that his heart will not be lifted up above his countrymen [by a false sense of self-importance and self-reliance] and that he will not turn away (deviate) from the commandment, to the right or to the left, so that he and his sons may continue [to reign] for a long time in his kingdom in Israel.

You shall give him his wages on the day that he earns them before the sun sets—for he is poor and is counting on it—so that he does not cry out to the Lord against you, and it becomes a sin for you.

“This day the Lord your God commands you to do these statutes and judgments (precepts). Therefore, you shall be careful to do them with all your heart and with all your soul (your entire being).

The Lord will strike you with madness and with blindness and with bewilderment of heart and mind;

“Because you did not serve the Lord your God with a heart full of joy and gladness for the abundance of all things [with which He blessed you],

Among those nations you will find no peace (rest), and there will be no resting place for the sole of your foot; but there the Lord will give you a trembling heart, failing eyes, and a despairing soul.

It will happen that when he (a renegade) hears the words of this oath, and he imagines himself as blessed, saying, ‘I will have peace and safety even though I walk within the stubbornness of my heart [rejecting God and His law], in order that the watered land dwindles away along with the dry [destroying everything],’
