See how you translated this in [Matthew 13:24](../13/24.md). Alternate translation: "When our God in heaven shows himself to be king, it will be like" (See: [[rc://en/ta/man/jit/figs-metonymy]])
Say "a large amount of flour" or use a term that your culture uses for measuring large amounts of flour. (See: [[rc://en/ta/man/jit/translate-bvolume]])
