The verses below are the beginning of a song which GOD gave to Moses for the benefit of His people. Today’s  reading is Deuteronomy 30 – 32.

Give ear, O ye heavens, and I will speak; and hear, O earth, the words of my mouth.  My doctrine shall drop as the rain, my speech shall distil as the dew, as the small rain upon the tender herb, and as the showers upon the grass: because I will publish the name of the LORD: ascribe ye greatness unto our God.
He is the Rock, His work is perfect: for all His ways are judgment: a God of truth and without iniquity, just and right is He.
They have corrupted themselves, their spot is not the spot of His children: they are a perverse and crooked generation.  Do ye thus requite the LORD, O foolish people and unwise? Is not He thy father that hath bought thee? Hath He not made thee, and established thee?
Deuteronomy 32:1-6
