Isaiah 37:38

As he was worshipping -Perhaps this time was selected because he might be then attended with fewer guards, or because they were able to surprise him without the possibility of his summoning his attendants to his rescue. In the house -In the temple. Of Nisroch his god -The god whom he particularly adored. Gesenius supposes that the word ‘Nisroch’ denotes an eagle, or a great eagle. The eagle was regarded as a sacred bird in the Persian religion, and was the symbol of Ormuzd. This god or idol had been probably introduced into Nineveh from Persia. Among the ancient Arabs the eagle occurs as an idol Josephus calls the idol Araskes; the author of the book of Tobit calls it Dagon.
