Here "Israel" is a metonym for the men of Israel. The word "all" is a generalization. AT: "the men of Israel were coming" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-hyperbole]])
These are the names of men. See how you translated these names in [2 Chronicles 9:29](../09/29.md). (See: [[rc://en/ta/man/translate/translate-names]])
