The historical context of Isaiah is the Neo-Assyrian Empire of the eighth and seventh centuries before Christ.----In keeping with the prophecies regarding the threats out of Samaria and Damascus in Isaiah chapters 7 and 8, the Assyrian Empire had invaded Syria and Israel, destroying Israel's capital, Samaria in 722, under King Sargon II.----Now, the ungodly king of Judah, Ahaz, has been succeeded by his godly son, Hezekiah, and the new ruler of Assyria, Sennacherib was on the move against Judah.----When Sennacherib's representatives communicate with the representatives of Hezekiah, they shout out in Hebrew to the men on the wall in order to terrorize them -Isaiah 36-11-20-.----In keeping with the curse section in Deuteronomy, whenever God's people had been surrounded by enemy armies, they experienced the omen that the curses recorded there were about to happen- -The LORD will bring a nation against you from far away . . . a nation whose language you will not understand- -Deuteronomy 28-49-.----Isaiah has this in mind as he responds to the unbelievers in Jerusalem by repeating infantile gibberish twice- -Sav lasav, sav lasav, Kav lakav, kav lakav, Ze' er sham, ze' er sham- -Isaiah 28-10, 13-. As with his earlier words to King Ahaz, Isaiah is warning the unbelievers they were about to hear people speaking in languages they could not understand, languages that sounded like baby-talk.----Reading what follows this omen is chilling -Deuteronomy 28-53-57-.
