Yahweh has given
Joas is a biblical name derived from the Hebrew name Yoash, meaning 'Yahweh has given' or 'fire of Yahweh'. In the Old Testament, it is a variant form of Jehoash, the name of several kings of Israel and Judah. While rare in modern English-speaking countries, it remains a traditional choice in Dutch and Portuguese contexts.
