Then Amaziah sent messengers to Jehoash, the son of Jehoahaz son of Jehu, king of Israel, saying: ‘Come, let us look one another in the face.’
Rashi on II Kings
Amatzyoh then sent messengers, etc., “let us battle each other.” [By going] to war.3Previously, Yehoash’s men had invaded Yehudah in a surprise attack, because Amatzyohu had abruptly dismissed Yehoash’s men from going to war with him. See II Divrei Hayomim 25:10, 13. Amatzyohu now challenged Amatzyohu to confront him in battle.—Metzudas Dovid
