Ver. 17. Casiphia— It is not easy to guess what place this was. The text calls it Casiphia the place. Some have taken it for the Caspian mountains situate between Media and Hyrcania, in the mines of which these captive Nethinims are supposed to have been sent to work; if so, it is no wonder that they should be so ready to embrace the benefit of the king's decree. The LXX render it a place of silver; for ףּכס keseph signifies silver.
