Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The following commentary covers Chapters 12 and 13.
We have already seen that gladness was the portion of the people; a joy which acknowledged God, for God had preserved the people and had blessed them. But the princes of the people had immediately relapsed into unfaithfulness; and during Nehemiah's absence the chambers of the temple, in which the offerings had been formerly kept, were given up to Tobiah, that subtle and persevering enemy of God's people. But at the dedication of the wall of Jerusalem the joy of the people and the faithfulness of Nehemiah brought them back to the written word, and Israel separated themselves again from the mixed multitude. Tobiah's stuff is cast out of the chamber prepared for him in the temple. The observance of the Sabbath is again enforced. Those who had married strange wives, and whose children spake partly the language of strangers and partly that of the Jews, are put under the curse and sharply rebuked and chastised. The order and the cleansing, according to the law, are re-established, and this leading thought of the book, as to the people's condition, closes the narrative. That which we have said will give an idea of the great principle of this book. I will add a few more remarks in this place.
