“G-d is not man to be capricious, or mortal to change His mind. Would He speak and not act, promise and not fulfill?” – Numbers 23:21, JPS 1985 Tanach
As paraphrased by the Targum, “The Word of the living G-d is not as the words of men for the L-rd, the Ruler of all worlds, is the unchangeable, (but) man speaketh and denieth. Neither are His works like the works of the children of flesh, who consult, and then repent them of what they had decreed” (Targum Jonathan on Numbers 23:19, sefaria.org). In other words, that they change their mind, instead of remaining committed to their original intended course of action.
R’ Bachya states, in no uncertain terms that “the essential difference between G’d and man is that G’d keeps His promises whereas man often deceives, [and] disappoints the people who have been promised by him” (sefaria.org). Moreover, “Whereas man may change his mind concerning matters he had planned, which did not involve undertakings to his fellow man, he nonetheless is apt to have remorse, to change his mind before executing his plan” (sefaria.org).
Additionally, “when man deceives or reneges, this is considered a serious flaw in his character” (sefaria.org). Therefore, it may is important to keep in mind, based upon this commentary the benefits, of focusing upon character development, integrity, and keeping one’s word. These are all positive qualities to work on obtaining in life. Moreover, that our own words, should not contradict each other, as if we had two selves, in conflict with each other. And, that are actions should also not be opposed to our values, beliefs, and goals.
