THOU SHALT BE WHOLE-HEARTED WITH THE ETERNAL THY G-D. The meaning thereof is that we are to direct our hearts to Him only, and believe that He alone does everything. It is He Who knows the truth about all future events, and from His prophets, or from His pious ones, in other words the Urim and Thummim193Exodus 28:30 (Vol. II, pp. 480-483). — are we to inquire about future events. We are not to inquire of the astrologers or from anyone else, or by any means to trust that their words will be fulfilled. Instead, if we hear any prediction [of the diviners] we should say, “Everything is in the hands of Heaven,194Berachoth 33b. for He is the G-d of gods195Above, 10:17. Who is supreme above all, the Omnipotent One over everything, Who changes the set order of the stars and constellations at His Will, Who frustrateth the tokens of the imposters, and maketh diviners mad,”196Isaiah 44:25. and we are to believe that future events will occur according to man’s drawing closer to His service. Therefore after the warning against inquiring about future events from diviners, and of seeking on behalf of the living to the dead,197Isaiah 8:19. he stated that you are to be whole-hearted with G-d in all these matters and not be afraid of those who tell of things to come. Rather, you should inquire of His prophet and to him shall you hearken.185Verse 15. And this is the opinion of Onkelos who translated, “You shall be whole-hearted in the fear of the Eternal your G-d,” meaning that you should not be deficient in the fear of Him, for tamim (whole) indicates perfection in a thing, just as ‘seh tamim’ (a lamb that is perfect)198Exodus 12:5. means one that is without blemish and any deficiency. This verse [before us] constitutes a positive commandment.199So also mentioned by Ramban in his notes to Rambam’s Sefer Hamitzvoth. See my translation of “The Commandments,” Vol. I, p. 264, Commandment 8. I have already mentioned this in connection with the verse, and be thou whole-hearted.200Genesis 17:1 (Vol. I, p. 217).
