ייִדישער מחשבֿה אויף תהילים 100:3

And David said: "Know you that the L-ord He is G-d" (Ps. 100:3).

we will therefore return to the subject of this chapter, and exhort those who have attained a knowledge of God, to concentrate all their thoughts in God. This is the worship peculiar to those who have acquired a knowledge of the highest truths; and the more they reflect on Him, and think of Him, the more are they engaged in His worship. Those, however, who think of God, and frequently mention His name, without any correct notion of Him, but merely following some imagination, or some theory received from another person, are, in my opinion, like those who remain outside the palace and distant from it. They do not mention the name of God in truth, nor do they reflect on it. That which they imagine and mention does not correspond to any being in existence: it is a thing invented by their imagination, as has been shown by us in our discussion on the Divine Attributes (Part I. chap. 1.). The true worship of God is only possible when correct notions of Him have previously been conceived. When you have arrived by way of intellectual research at a knowledge of God and His works, then commence to devote yourselves to Him, try to approach Him and strengthen the intellect, which is the link that joins you to Him. Thus Scripture says, “Unto thee it was showed, that thou mightest know that the Lord He is God” (Deut. 4:35); “Know therefore this day, and consider it in thine heart, that the Lord He is God” (ibid. 36); “Know ye that the Lord is God” (Ps. 100:3). Thus the Law distinctly states that the highest kind of worship to which we refer in this chapter, is only possible after the acquisition of the knowledge of God. For it is said, “To love the Lord your God, and to serve Him with all your heart and with all your soul” (Deut. 11:13), and, as we have shown several times, man’s love of God is identical with His knowledge of Him. The Divine service enjoined in these words must, accordingly, be preceded by the love of God. Our Sages have pointed out to us that it is a service in the heart, which explanation I understand to mean this: man concentrates all his thoughts on the First Intellect, and is absorbed in these thoughts as much as possible. David therefore commands his son Solomon these two things, and exhorts him earnestly to do them: to acquire a true knowledge of God, and to be earnest in His service after that knowledge has been acquired. For he says, “And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart . . . if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever” (1 Chron. 28:9). The exhortation refers to, the intellectual conceptions, not to the imaginations: for the latter are not called “knowledge,” but “that which cometh into your mind” (Ezek. 20:32). It has thus been shown that it must be man’s aim, after having acquired the knowledge of God, to deliver himself up to Him, and to have his heart constantly filled with longing after Him. He accomplishes this generally by seclusion and retirement. Every pious man should therefore seek retirement and seclusion, and should only in case of necessity associate with others.
