So the Israelites were brought low at that time, and the men of Judah prevailed, because they had leaned on Yahweh, the God of their ancestors.
In context
16Israel took flight before Judah, and God handed them over. 17Abijah and his troops dealt them a crushing blow: five hundred thousand picked men of Israel fell slain. 18So the Israelites were brought low at that time, and the men of Judah prevailed, because they had leaned on Yahweh, the God of their ancestors. 19Abijah pursued Jeroboam and took towns from him: Bethel with its villages, Jeshanah with its villages, and Ephrain with its villages. 20Jeroboam never recovered his strength in the days of Abijah; and Yahweh struck him down, and he died.
