It is interesting that he does not even say "the Ten Commandments." He starts out with what we might consider to be "the little things." Of course, we understand that the commandments are included within them. So he establishes, secondarily, that he understands, before God, the reasons why Judah went into captivity and was scattered. Please apply this to the church. This did not "just happen," as if there was no cause. "The curse causeless shall not come," Proverbs 26:2 says. We come under a curse because we have sinned.
