For Israel has forgotten his Maker and built palaces; And Judah has multiplied fortified cities; But I will send a fire on his cities, And it will devour its fortresses."
The mention of castles and fortified cities speaks of a people relying upon themselves rather than upon God. Also, in the case of Israel there seems to have been an inordinate glorying in such human achievements, as attested by the long and tedious records of the Kings and Chronicles of the Old Testament.  Again from Hindley, "Human achievement is not always to the glory of God."[30]
