Here the people of Israel are spoken of as God's inheritance. Alternate translation: "your special people" (See: [[rc://en/ta/man/translate/figs-metaphor]])
This can be translated as a statement. Alternate translation: "Other nations should not be able to say, 'Their God does not help them.'" or "Other nations should not be able to say that the God of Israel has abandoned his people." (See: [[rc://en/ta/man/translate/figs-rquestion]])
