The Hebrew name Be'erah means 'well' or 'well of Jah (God).' It is the name of a Reubenite prince carried into exile by Tiglath-pileser king of Assyria (1 Chronicles 5:6). While a minor figure, his story illustrates the covenant consequences of unfaithfulness.
The exile of Reubenite leaders like Be'erah in 1 Chronicles 5 is presented as the direct result of Israel's unfaithfulness to God: 'they broke faith with the God of their fathers and whored after the gods of the peoples of the land.' The deportations of individual leaders are not random political events but the outworking of God's covenant promises, both in blessing for obedience and in judgment for covenant breaking. The name 'well of God' (Be'er Yah) is ironic — this prince of a tribe named after the firstborn son of Jacob was 'dried up' by exile.
