וַיַּ֨עַל יוֹאָ֤שׁ מֶֽלֶךְ־יִשְׂרָאֵל֙ וַיִּתְרָא֣וּ פָנִ֔ים ה֖וּא וַאֲמַצְיָ֣הוּ מֶֽלֶךְ־יְהוּדָ֑ה בְּבֵ֥ית שֶׁ֖מֶשׁ אֲשֶׁ֥ר לִיהוּדָֽה׃
И пошел Иоас, царь Израильский; и он и Амасия, царь Иудейский, смотрели друг другу в лицо в Вифлееме, который принадлежит Иудее.
Rashi on II Chronicles
in Beth-Shemesh the war took place. It was necessary to say this lest you ask why they brought Amaziah to Jerusalem and not to Samaria when they seized him. [The answer is] that Beth-Shemesh was near Jerusalem.
