Comentario sobre Deuteronómio 8:5

AND THOU SHALT CONSIDER IN THY HEART, THAT, AS A MAN CHASTENETH HIS SON, placing upon him the yoke of instruction for his benefit, as it is said, Chasten thy son, for there is hope; but set not thy heart on his destruction⁷⁵Proverbs 19:18. — SO THE ETERNAL THY G-D CHASTENETH THEE, at first with the affliction of the wilderness and the trial with the manna so that the goodness of the Land and its fruits should be pleasing to you. Therefore walk after Him, for the Eternal thy G-d bringeth thee into a good Land.⁷⁶Verse 7.

מיסרך; along with the commandments He has given you, He gives you a superior moral/ethical challenge to help you achieve perfection as seen from His perspective.

וידעת עם לבבך, "You shall know in your heart, etc." This verse reminds a person to reflect that generally speaking no one makes a point of admonishing and disciplining anyone except his own son, as he is not nearly as interested in the education of others as he is in educating his own son. When a person observes his friend's son commit a wrong he is not as much concerned about this as when the wrong is committed by his own son. When we observe G'd disciplining a Jew this is proof that G'd relates to such a Jew as a father relates to a son. When G'd observes the Gentile nations commit all kinds of abominations, He does not react in the same way as He reacts to sins committed by the Jewish people because He does not relate to the Gentiles in the same way, i.e. as a father. He has not associated His name in an exclusive manner with the Gentiles as He has done with us. This is why He demonstrates His concern every time we depart from the norms of behaviour laid down for us.
