Taskmasters - The Egyptian “Chiefs of tributes.” They were men of rank, superintendents of the public works, such as are often represented on Egyptian monuments, and carefully distinguished from the subordinate overseers. The Israelites were employed in forced labor, probably in detachments, but they were not reduced to slavery, properly speaking, nor treated as captives of war. Amosis had special need of such laborers, as proved by the inscriptions.
Treasure cities - “Magazines,” depots of ammunition and provisions 1 Kings 9:19; 2 Chronicles 8:4; 2 Chronicles 32:28.
Pithom and Raamses - Both cities were situated on the canal which was dug or enlarged in the 12th Dynasty. The former is known to have existed under the 18th Dynasty. Both were in existence at the beginning of the reign of Rameses II, by whom they were fortified and enlarged. The name “Pithom” means “House or temple of Tum,” the Sun God of Heliopolis (see Exodus 13:20). The name of Raamses, or Rameses, is generally assumed to have been derived from Rameses II, the Sesostris of the Greeks, but it was previously known as the name of the district. See Genesis 45:10; Genesis 47:11.
