English Basic Explanation - Chapter 147
Towards the beginning of this chapter David gives praise to God for "building Jerusalem" and "gathering the exiles of Israel" (verse 2), clearly indicating that he refers here to the period of the final redemption. At that time God will "heal" the "broken hearts" (verse 3) of the Jewish people who had suffered for so many centuries from exile and oppression, and transform their pain to joy, and their sorrow to celebration. Moreover, the advent of redemption will demonstrate that although God's greatness and power is unparalleled, His primary concern is rescuing the lowly, oppressed people from the cruel tyrants of the world, and caring for all creatures, including even the animals and birds (verses 4-9).
The second half this chapter (verses 12-20) describes the many blessings that God will bestow upon the Jewish people after their return to Zion. David speaks here of the safety and security enjoyed by the people of Jerusalem, as well as the material prosperity resulting from abundant rainfall and snowfall. As the Torah mentions on a number of occasions, the amount of rainfall in the Land of Israel serves as an indicator of Am Yisrael's status vis-à-vis God, whether or not we are deserving of His blessings and kindness. David describes here the copious amounts of rain that will descend upon Israel in the Messianic era, signifying the close relationship that will exist between the Almighty and the Jewish people at that time.
The final item on this list of kindnesses is God's singling out Am Yisrael as the nation worthy of receiving His Torah (verses 19-20). At the time of the final redemption we will experience overwhelming joy and gratitude over the privilege we have been granted to study and practice God's laws, and recognize how our commitment to those laws brings us blessing and success. Whereas in our current situation the benefits of Torah learning and observance are not readily obvious to one and all, in the time of Mashiah the entire nation will join together in praising and thanking the Almighty for this great privilege. All will acknowledge that the Torah affords us the unique opportunity to achieve closeness with God and earn His favor and grace, which will be felt and manifest most clearly in the rebuilt Temple and the return of the Divine Presence to our midst.
