Theodoret of Cyrus
What is the scripture of righteousness? It is clear that the account of the kings is derived from various prophetic writings. The author noted in his lamentation that it is recorded in the book of the Just.
(Also he commanded that they should teach the children of Juda the use of the bow, as it is written in the book of the just.) And he said: Consider, O Israel, for them that are dead, wounded on thy high places.
וַיֹּ֕אמֶר לְלַמֵּ֥ד בְּנֵֽי־יְהוּדָ֖ה קָ֑שֶׁת הִנֵּ֥ה כְתוּבָ֖ה עַל־סֵ֥פֶר הַיָּשָֽׁר׃
