[4] "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. This psalm manifestly foretells the time of the Machabees, and the profanation of the temple by Antiochus.
[13] "The sea firm": By making the waters of the Red Sea stand like firm walls, whilst Israel passed through: and destroying the Egyptians called here dragons from their cruelty, in the same waters, with their king: casting up their bodies on the shore to be stripped by the Ethiopians inhabiting in those days the coast of Arabia.
[15] "Ethan rivers": That is, rivers which run with strong streams. This was verified in Jordan, Jos. 3, and in Arnon, Num. 21. 14.
[20] "The obscure of the earth": Mean and ignoble wretches have been filled, that is, enriched, with houses of iniquity, that is, with our estates and possessions, which they have unjustly acquired.
