Zechariah Dhahiri
Zechariah (Yaḥya) al-Ḍāhirī (, , b. "circa" 1531 – d. 1608), often spelled Zechariah al-Dhahiri () (16th century Yemen), was the son of Saʻīd (Saʻadia) al-Ḍāhirī, from Kawkaban, in the District of al-Mahwit, Yemen, a place north-west of Sana’a. He is recognized as one of the most gifted Yemenite Jewish poets and rabbinic scholars who left Yemen in search of a better livelihood, travelling to Calicut and Cochin in India, Hormuz in Persia, Basra and Irbīl in Babylonia, Bursa and Istanbul in Anatolia, Rome in Italy, Aleppo and Damascus in Syria, Safed and Tiberias, as well as Jerusalem and Hebron in the Land of Israel (then part of Ottoman Syria), Sidon in Ottoman Lebanon and Egypt, and finally unto Abyssinia where he returned to Yemen by crossing the Erythraean Sea and alighting at a port city near Mocha, Yemen. He wrote extensively about his travels and experiences in these places, which he penned in a Hebrew rhymed prose narrative, and eventually publishing them in a book which he called Sefer Ha-Mūsar ("The Book of Moral Instruction"), in circa 1580.
Hezekiah
As an example of the reasoning that finds inconsistencies in calculations when coregencies are "a priori" ruled out, dates the fall of Samaria (the Northern Kingdom) to the 6th year of Hezekiah's reign. William F. Albright has dated the fall of the Kingdom of Israel to 721 BC, while E. R. Thiele calculates the date as 723 BC. If Abright's or Thiele's dating are correct, then Hezekiah's reign would begin in either 729 or 727 BC. On the other hand, states that Sennacherib invaded Judah in the 14th year of Hezekiah's reign. Dating based on Assyrian records date this invasion to 701 BC, and Hezekiah's reign would therefore begin in 716/715 BC. This dating would be confirmed by the account of Hezekiah's illness in chapter 20, which immediately follows Sennacherib's departure (). This would date his illness to Hezekiah's 14th year, which is confirmed by Isaiah's statement () that he will live fifteen more years (29 − 15 = 14). As shown below, these problems are all addressed by scholars who make reference to the ancient Near Eastern practice of coregency.
