Kings II 21:16 Meaning and Commentary

2 Kings 21:16

Moreover, Manasseh shed innocent blood very much
Putting to death the prophets that reproved him and his people for their idolatries, and such who would not comply therewith; and it is commonly said, both by Jewish and Christian writers, that Isaiah was slain, and even sawn asunder by him, (See Gill on Hebrews 11:37),

till he had filled Jerusalem from one end to another;
a metaphor taken from filling a vessel brimful:

beside his sin wherewith he made Judah to sin, in doing that which was
evil in the sight of the Lord;
the sin of idolatry he drew them into, and even obliged them to commit.
