16 The Lord aroused against Jehoram the hostility of the Philistines and of the Arabs who lived near the Cushites.
7 But when Sanballat, Tobiah, the Arabs, the Ammonites and the people of Ashdod heard that the repairs to Jerusalem's walls had gone ahead and that the gaps were being closed, they were very angry.
(Read Nehemiah 4:7-15)
The hindering good work is what bad men aim at, and promise themselves success in; but good work is God's work, and it shall prosper. God has many ways of bringing to light, and so of bringing to nought, the devices and designs of his church's enemies. If our enemies cannot frighten us from duty, or deceive us into sin, they cannot hurt us. Nehemiah put himself and his cause under the Divine protection. It was the way of this good man, and should be our way. All his cares, all his griefs, all his fears, he spread before God. Before he used any means, he made his prayer to God. Having prayed, he set a watch against the enemy. If we think to secure ourselves by prayer, without watchfulness, we are slothful, and tempt God; if by watchfulness, without prayer, we are proud, and slight God: either way, we forfeit his protection. God's care of our safety, should engage and encourage us to go on with vigour in our duty. As soon as a danger is over, let us return to our work, and trust God another time.

Commentary on 2 Chronicles 21:12-20
(Read 2 Chronicles 21:12-20)
A warning from God was sent to Jehoram. The Spirit of prophecy might direct Elijah to prepare this writing in the foresight of Jehoram's crimes. He is plainly told that his sin should certainly ruin him. But no marvel that sinners are not frightened from sin, and to repentance, by the threatenings of misery in another world, when the certainty of misery in this world, the sinking of their estates, and the ruin of their health, will not restrain them from vicious courses. See Jehoram here stripped of all his comforts. Thus God plainly showed that the controversy was with him, and his house. He had slain all his brethren to strengthen himself; now, all his sons are slain but one. David's house must not be wholly destroyed, like those of Israel's kings, because a blessing was in it; that of the Messiah. Good men may be afflicted with diseases; but to them they are fatherly chastisements, and by the support of Divine consolations the soul may dwell at ease, even when the body lies in pain. To be sick and poor, sick and solitary, but especially to be sick and in sin, sick and under the curse of God, sick and without grace to bear it, is a most deplorable case. Wickedness and profaneness make men despicable, even in the eyes of those who have but little religion.
