Transibo Aegyptum et in Soccoth atque apud fontem Samson, quem de molari maxillae dente produxit, subsistam parumper et arentia ora conluam, ut refocilatus videam Morasthi, sepulchrum quondam Micheae prophetae, nunc ecclesiam.
(Hieronymus, Ep. 108 - Peregr. Paulae, 14)
Hieronymus, Ep. 108 (Peregrinatio Paulae) 14 (385 A.D.)
So I shall pass on towards Egypt and pause for a moment at Soccoth and near the Spring of Samson which he made to come forth with the molar tooth of the jawbone, and I will hold my dry mouth to it so that I may be refreshed to see Morasthi, once the tomb of Michah the prophet, now a church.
Jer. 26:16-19 Jeremiah relates one of Micah's profecies
Then the officials and all the people said to the priests and the prophets, "This man does not deserve the sentence of death, for he has spoken to us in the name of the Lord our God." And some of the elders of the land arose and said to all the assembled people, "Micah of Moresheth, who prophesied during the days of King Hezekiah of Judah, said to all the people of Judah: 'Thus says the Lord of hosts, Zion shall be plowed as a field; Jerusalem shall become a heap of ruins, and the mountain of the house a wooded height.' Did King Hezekiah of Judah and all Judah actually put him to death? Did he not fear the Lord and entreat the favor of the Lord, and did not the Lord change his mind about the disaster that he had pronounced against them? But we are about to bring great disaster on ourselves!"
Mic 1:1 The prophet Micah
The word of the Lord that came to Micah of Moresheth in the days of Kings Jotham, Ahaz, and Hezekiah of Judah, which he saw concerning Samaria and Jerusalem.
