Deuteronomy 10:20

After laying down the fundamental condition of a proper relation towards God, Moses describes the fear of God, i.e., true reverence of God, in its threefold manifestation, in deed (serving God), in heart (cleaving to Him; cf. Deu 4:4), and with the mouth (swearing by His name; cf. Deu 6:13). Such reverence as this Israel owed to its God; for "He is thy praise, and He is thy God" (Deu 10:21). He has given thee strong inducements to praise. By the great and terrible things which thine eyes have seen, He has manifested Himself as God to thee. "Terrible things" are those acts of divine omnipotence, which fill men with fear and trembling at the majesty of the Almighty (cf. Exo 15:11). אתּך עשׂה, "done with thee," i.e., shown to thee (את in the sense of practical help).

Moses having, in the foregoing chapter, reminded them of their own sin, as a reason why they should not depend upon their own righteousness, in this chapter he sets before them God's great mercy to them, notwithstanding their provocations, as a reason why they should be more obedient for the future. I. He mentions divers tokens of God's favour and reconciliation to them, never to be forgotten. (1.) The renewing of the tables of the covenant (Deu 10:1-5). (2.) Giving orders for their progress towards Canaan (Deu 10:6, Deu 10:7). (3.) Choosing the tribe of Levi for his own (Deu 10:8, Deu 10:9). (4.) And continuing the priesthood after the death of Aaron (Deu 10:6). (5.) Owning and accepting the intercession of Moses for them (Deu 10:10, Deu 10:11). II. Hence he infers what obligations they lay under to fear, and love, and serve God, which he presses upon them with many motives (Deu 10:12, etc.).
