International Standard Bible Encyclopedia [2]

pir´a - mid πυραμίς , puramı́s  : Pyramids are mentioned in connection with the splendid monument reared by Simon Maccabeus in memory of his parents and brethren at Modin (  1 Maccabees 13:28; compare Ant. , 13 vi, 6). Josephus describes them as "very surprising, both for their largeness and beauty." There is nothing to show how the pyramid allotted to each was distinguished, whether by difference in size or by inscriptions. It is remarkable that in Scripture there is no allusion to the giant structures in Egypt; but these may have supplied the suggestion to Simon's mind.
