And when he heard of Theraca king of Ethiopia: Behold, he is come out to fight with thee: and was going against him, he sent messengers to Ezechias, saying:

And he heard say of Tirhakah king of Ethiopia, Behold, he has come forth to make war with thee. And he sent messengers again to Hezekiah, saying,

And when he heard it said of Tirhakah king of Cush, Behold, he hath come out to fight against thee: he sent messengers again to Hezekiah, saying,

And he heareth concerning Tirhakah king of Cush, saying, 'Lo, he hath come out to fight with thee;' and he turneth and sendeth messengers unto Hezekiah, saying,

And when news came to him that Tirhakah, king of Ethiopia, had made an attack on him, he sent representatives to Hezekiah again, saying,

And when he had heard from Tirhakah, the king of Ethiopia, saying, "Behold, he has gone out so that he may fight against you," and when he went forth against him, he sent messengers to Hezekiah, saying:

Tirhakah king of Ethiopia - The Tehrak or Teharka of the hieroglyphics. He was the last king of the 25th or Ethiopian dynasty, which commenced with Shebek or Sabaco, and he reigned upward of 26 years. The Assyrian inscriptions show that he still ruled in Egypt as late as 667 B.C., when Esarhaddon 2-Kings 19:37 died, and his son Asshur-bani-pal succeeded him. He probably ascended the Egyptian throne about 692 B.C., having previously ruled over Ethiopia before he became king of Egypt (compare Isaiah 37:9). Thus he was probably reigning in Ethiopia at the time of Sennacherib's expedition, while Sethos and perhaps other secondary monarchs bore rule over Egypt. His movements caused Sennacherib to send a second embassy, instead of marching in person against the Jewish king.

And when (e) he heard say of Tirhakah king of Ethiopia, (f) Behold, he is come out to fight against thee: he sent messengers again unto Hezekiah, saying,
(e) That is, Sennacherib.
(f) For the kings of Ethiopia and Egypt joined together against the king of Assyria because of his oppression of other countries.

when he heard say of Tirhakah . . ., Behold, he is come out to fight against thee, &c.--This was the "rumor" to which Isaiah referred [2-Kings 19:7]. Tirhakah reigned in Upper Egypt, while So (or Sabaco) ruled in Lower Egypt. He was a powerful monarch, another Sesostris, and both he and Sabaco have left many monuments of their greatness. The name and figure of Tirhakah receiving war captives, are still seen in the Egyptian temple of Medinet Abou. This was the expected succor which was sneered at by Rab-shakeh as "a bruised reed" (2-Kings 18:21). Rage against Hezekiah for allying himself with Egypt, or the hope of being better able to meet this attack from the south, induced him, after hearing the rumor of Tirhakah's advance, to send a menacing letter to Hezekiah, in order that he might force the king of Judah to an immediate surrender of his capital. This letter, couched in the same vaunting and imperious style as the speech of Rab-shakeh, exceeded it in blasphemy, and contained a larger enumeration of conquered places, with the view of terrifying Hezekiah and showing him the utter hopelessness of all attempts at resistance.

There Sennacherib heard that Tirhakah was advancing to make war against him. Tirhakah, Θαρακά (lxx), king of Cush, is the Ταρακός of Manetho, the successor of Sevechus (Shebek II), the third king of the twenty-fifth (Ethiopian) dynasty, described by Strabo (xv. 687), who calls him Τεάρκων, as a great conqueror. His name is spelt Thlqa or Tharqo upon the monuments, and on the Pylon of the great temple at Medinet-Abu he is represented in the form of a king, cutting down enemies of conquered lands (Egypt, Syria, and Tepop, an unknown land) before the god Ammon (see Brugsch, hist. d'Egypte, i. pp. 244,245).
(Note: According to Jul. Afric. (in Syncell. i. p. 139, ed. Dind.) he reigned eighteen years, according to Euseb. (in Syncell. p. 140) twenty years. Both statements are incorrect; for, according to an Apis-stele published by Mariette, the birth of an Apis who died in the twentieth year of Psammetichus fell in the twenty-sixth year of Tirhakah, so that the reign of Tirhakah may be supposed to have lasted twenty-eight years (see Brugsch, l.c. p. 247). But the chronological conclusions respecting the date of his reign are very uncertain. Whereas M. v. Niebuhr (Gesch. Ass. p. 72) fixes his expedition against Sennacherib in the thirty-seventh aer. Nab., i.e., 710 b.c., and the commencement of his reign over Egypt in 45 aer. Nab., i.e., 702 b.c., and assumes that he marched against Sennacherib before he was king of Egypt, which is apparently favoured by the epithet king of Cush, not of Egypt; Brugsch (l.c. p. 292) has given the year 693 b.c. as the commencement of his reign. It is obvious that this statement is irreconcilable with the O.T. chronology, since the fourteenth year of Hezekiah, in which Sennacherib invaded Judah, corresponds to the year 714 or 713 b.c. These diversities simply confirm our remark (p. 411), that the chronological data as to the kings of Egypt before Psammetichus cannot lay any claim to historical certainty. For an attempt to solve this discrepancy see M. v. Niebuhr, pp. 458ff.)
- On hearing the report of the advance of Tirhakah, Sennacherib sent ambassadors again to Hezekiah with a letter (2-Kings 19:14), in which he summoned him once more to give up his confidence in his God, and his assurance that Jerusalem would not be delivered into the hands of the king of Assyria, since the gods of no other nation had been able to save their lands and cities from the kings of Assyria who had preceded him. The letter contained nothing more, therefore, than a repetition of the arguments already adduced by Rabshakeh (2-Kings 18:19.), though a larger number of the lands conquered by the Assyrians are given, for the purpose of strengthening the impression intended to be made upon Hezekiah of the irresistible character of the Assyrian arms. - To offer a successful resistance to Tirhakah and overcome him, Sennacherib wanted above all things a firm footing in Judah; and for this the possession of Jerusalem was of the greatest importance, since it would both cover his back and secure his retreat. Fortifications like Lachish and Libnah could be quickly taken by a violent assault. But it was very different with Jerusalem. Salmanasar had stood before Samaria for three years before he was able to conquer it; and Nebuchadnezzar besieged Jerusalem for two years before the city was starved out and it was possible to take it (2-Kings 25:1.). But as Tirhakah was approaching, Sennacherib had no time now for so tedious a siege. He therefore endeavoured to induce Hezekiah to surrender the city quietly by a boastful description of his own power. Instead of ויּשׁלח ויּשׁב (2-Kings 19:9), we have in Isaiah ויּשׁלח ויּשׁמע, "when he heard this he sent," which is probably the more original, and indicates that when Sennacherib received the intelligence he sent at once (Drechsler).
