Melachim Bais 20:5

5 Shuv (return), and say to Chizkiyahu (Hezekiah) the Nagid Ami, Thus saith Hashem Elohei Dovid Avicha, I have heard thy tefillah, I have seen thy tears; hineni, I will heal thee; on Yom HaShelishi thou shalt go up unto the Beis Hashem.

Melachim Bais 20:5 Meaning and Commentary

Turn again, and tell Hezekiah the captain of my people,.... The king of them, as the Targum:

thus saith the Lord God of David thy father, I have heard thy prayer, I have seen thy tears; See Gill on "Isa 38:5"

behold, I will heal thee; instantly, miraculously; and none but God could heal him, his disease being in its kind mortal, and he had been told from the Lord that he should die:

on the third day thou shalt go up unto the house of the Lord: the temple, to give thanks for his recovery; and this he should do on the third day from thence; so soon should he be well, which would show the cure to be miraculous.

Melachim Bais 20:5 In-Context

3 Remember now, Hashem, how I have walked before Thee in emes and with a lev shalem, and have done that which is hatov in Thy sight. And Chikiyahu (Hezekiah) wept with bekhi gadol (great weeping).

4 And it came to pass, before Yeshayah was gone out from the middle courtyard, that the Devar Hashem came to him, saying,

5 Shuv (return), and say to Chizkiyahu (Hezekiah) the Nagid Ami, Thus saith Hashem Elohei Dovid Avicha, I have heard thy tefillah, I have seen thy tears; hineni, I will heal thee; on Yom HaShelishi thou shalt go up unto the Beis Hashem.

6 And I will add unto thy days fifteen shanah; and I will save thee and this city out of the palm of Melech Asshur (Assyria); and I will defend this city for Mine Own sake, and for the sake of Dovid Avdi.

7 And Yeshayah said, Take a develet te’enim. And they took and laid it on the shechin (boil, inflamed spot) and he recovered [See Isaiah 38:21].
