2 Chronicles 20:22 - Exposition

Set ambushments . The Hebrew is נָתַן מְאָרְבִים , i.e. "set persons lying in wait," or "in ambush" (piel part. plur. of אָרַב ). So 9:25 , but kal participle with apparently future equivalent meaning occurs eighteen times in Joshua, Judges, Samuel, Ezra, Jeremiah, and Lamentations. Who the persons were, supernatural or not, or what their mode of operation, is not told, and is not plain. The effects are quite plain—that first the two confederates, Moab and Ammon, thought they saw reason to fall on them "of Mount Seir," and secondly, having this done, to fall on one another to the end of mutual extermination. They were smitten . The marginal, "they smote one another," may be better, but it is not at all necessary, the meaning being that collectively they became the smitten instead of the smiters!
