Halakhah sur Job 34:11

That which we have written on the prohibition of the diviner and the soothsayer (Sefer HaChinukh 249) is from the roots of this commandment. And [it is] since all of these nullities cause a person to leave the true fundamental religion and faith in God, may He be blessed; and to turn to emptiness and think that everything that happens to him, happens by way of circumstance; and that it is in his hand to better himself and remove all injury from him with those questions and nullities that he will do. And all of this is not worth it for him, since everything is decreed by the Master of the World. And according to the proper deed or the sin that a person does, do things occur to him - whether good or whether bad - and as it is written (Job 34:11), "For the action of a man does He pay to him." And upon this it is fitting for a person to order all of his thoughts and to prepare all of his ways. And this is the thought of every person of the good Children of Israel. And also, as there is a tinge of idolatry in this matter of ov and yidaaoni. The details of the commandment are in the seventh chapter of Sanhedrin (see Mishneh Torah, Laws of Foreign Worship and Customs of the Nations 6).
