מֵיהוָ֥ה מִצְעֲדֵי־גָ֑בֶר וְ֝אָדָ֗ם מַה־יָּבִ֥ין דַּרְכּֽוֹ׃
Langkah-langkah seseorang berasal dari Yang Mahakekal; maka bagaimana manusia dapat memahami jalannya sendiri?

1. God’s Providence extends over mankind severally, in as much as He had listened attentively (Psalms 116:2) to everything Job had said and had now come to argue with him and teach him some sense (Ecclesiastes 12:9). This testifies to the existence of individual Providence over all the steps a man takes (Psalms 37:23, Proverbs 20:24). Thus, Job’s thesis that God does not administer the world is refuted.

Furthermore, how can we charge our mind to choose this business or this trade? Many times we find one person becomes rich through this business or trade and it is good for him, while another person does not profit at all from it and it is bad for him. If so, there is no way for us to know, rather only that which G-d puts in our hearts [to choose] is for our good. We find many verses which teach this such as (Mishlei 19:21) "There are many plans in a man's heart but the counsel of the L-ord - that shall stand", and "A man's heart plans his way: but the L-ord directs his steps" (Mishlei 16:9), and (ibid 20:24) "A man's steps are directed by the L-ord; how then can anyone understand his own way", and many more verses. But the actions in the service of G-d, that which is good, namely, fulfilling the commandments - this is good forever and never changes. Likewise the negative commandments are always bad.
