until thy bowels fall out by reason of the sickness day by day;
that continuing day after day, and even year after year, the space of two years, as appears from ( 2 Chronicles 21:19 ) .

Chronicles II 21:15 In-Context

13 but hast walked in the ways of the kings of Israel, and hast caused Juda and the dwellers in Jerusalem to go a-whoring, as the house of Achaab caused to go a-whoring, and thou hast slain thy brethren, the sons of thy father, who were better than thyself;
14 behold, the Lord shall smite thee with a great plague among thy people, and thy sons, and thy wives, and all thy store:
15 and thou with a grievous disease, with a disease of the bowels, until thy bowels shall fall out day by day with the sickness.
16 So the Lord stirred up the Philistines against Joram, and the Arabians, and those who bordered on the Aethiopians:
17 and they went up against Juda, and prevailed against them, and took away all the store which they found in the house of the king, and his sons, and his daughters; and there was no son left to him but Ochozias the youngest of his sons.
