In Anathoth is the tower where the prophet Jeremiah uttered his Lamentations. It is four miles from Jerusalem. Twelve miles from Jerusalem is the tomb of the holy prophet Amos, at the place called Tekoa.
Cyrillus Scythopolitanus, Vita Sabae 36 (6th cent. A.D.)
The holy Elder observed their grievous state of distress - for they had neither a church nor a chief, but would take Communion on Sundays in the memorial of the holy prophet Amos in Thecoa, and besides, they were plunged in the disorder of anarchy, quarrelling and divided among themselves. (Sabas) pitied them and related their situation to the patriarch, asking him to organise them (in an orderly community).
Willibaldus, Vita 23 (724-726 A.D.)
After praying there [Bethlehem] they went on and arrive at a large village called Tekoa, the place where in old days the children had been murdered by Herod. A church is there now, and there is one of the Prophets buried there.
