Charles Ellicott Commentary 2 Chronicles 17:10

"And the fear of Jehovah fell upon all the kingdoms of the lands that were round about Judah, so that they made no war against Jehoshaphat." — 2 Chronicles 17:10 (ASV)

JEHOSHAPHAT BECOMES A POWERFUL SOVEREIGN.

The fear of the Lord. — A dread of Jehovah (pachad), Revelation 14:13;Revelation 20:29. (1 Samuel 11:7; Isaiah 2:10.) This phrase is not peculiar to the chronicler, as Keil and Bertheau assert. “The kingdoms of the lands” is so (2 Chronicles 12:8; 1 Chronicles 29:30).

They made no war. —The reward of Jehoshaphat’s piety (1 Chronicles 22:9; Proverbs 16:7): When a man’s ways please the Lord, he maketh even his enemies to be at peace with him.
