17 and they came up against Judah, broke into it, and carried away all the possessions that were found in the king’s house, including his sons and his wives, so that there was no son left to him except Jehoahaz, the youngest of his sons.
18 After all this the LORD struck him in his bowels with an incurable disease.
19 In process of time, at the end of two years, his bowels fell out by reason of his sickness, and he died of severe diseases. His people made no burning for him, like the burning of his fathers.
