AND BE THOU WHOLE-HEARTED. This is an additional commandment in this matter, similar in meaning to the verse, Thou shalt be whole-hearted with the Eternal thy G-d,³⁹²Ibid., 18:13. which follows G-d’s admonition: There shall not be found among you any one that … useth divination, a soothsayer, or an enchanter, or sorcerer, etc.³⁹³Ibid., Verse 10. The purport of both verses is that one should believe in his heart that the Holy One, blessed be He, alone is the Omnipotent from beginning to end. It is He who has the power to do and to undo, and therefore he should not listen to the soothsayers and diviners or to the enchanters and the sorcerers. He shall in no way believe that their words shall be fulfilled, but he should decree in his heart that everything is in the hand of the Supreme One, who is G-d, G-d Almighty, Who doeth a person good, which was not predestined by his constellation, and bringeth evil upon him despite a constellation that was good and auspicious. In accordance with the manner in which a man walks before Him, He frustrateth the tokens of the impostors, and maketh diviners mad.³⁹⁴Isaiah 44:25. It is this which the Sages had in mind when they said: “[G-d said to Abraham], ‘Go forth from your astrological speculations, etc.’”³⁹⁵See above, 15:5.
Now Rashi explained: “And be thou whole-hearted. Be whole-hearted in all the trials I impose upon you.” And Rabbi Abraham ibn Ezra said that the verse means that he should not seek the reason for the commandment of circumcision, it being similar in meaning to the verse: Let my heart be undivided in Thy statutes, in order that I may not be put to shame.³⁹⁶Psalms 119:80. The correct interpretation is as I have explained.

In the Midrash Rabbah on Exodus, parasha 19, it states, It is written: “Let my heart be undivided in your hukim [statutes] in order that I may not be put to shame.”⁵⁷Psalms 119:80. David said: “Lord of the universe! When I occupy myself with Your statutes, let not the Tempter have power to influence me, as it says: ‘Teach me, God, Your way, that I may walk in Your truth; [unite my heart to revere Your Name].’”⁵⁸Psalms 86:11.

[Discussing the Torah with others] benefits in two ways: First, if his mind is deviating from the truth and he errs in a matter, the students will redirect him, causing him to stand in truth. We previously quoted in chapter 8 the Midrash on Shemos how David’s request, “Let my heart be undivided in your hukim [statutes], in order that I may not be put to shame,”³⁵Psalms 119:80. [refers to] the students [detecting his error].
