The anger that the people have caused in Yahweh is extremely great.
# So his Lord will leave his blood on him
Here "blood" refers to the guilt incurred by people who murder others. God will not forgive their sins. (See: [[rc://en/ta/man/translate/figs-metonymy]])
The idea of making someone suffer the results of his own actions is spoken of as if those actions were objects that were thrown back at him. Alternate translation: "will make him suffer from his own disgraceful actions" (See: [[rc://en/ta/man/translate/figs-metaphor]])
