And they knew not both in the going out and on the highest top. As with axes in a wood of trees,
 "Their ensigns": They have fixed their colours for signs and trophies, both on the gates, and on the highest top of the temple: and they knew not, that is, they regarded not the sanctity of the place.

 "Ethan rivers": That is, rivers which run with strong streams. This was verified in Jordan, Jos. 3, and in Arnon, Num. 21. 14.
