All you inhabitants of the world and you dwellers on the earth

AT: "All you people on the earth." (See: rc://en/ta/man/translate/figs-parallelism)

when a signal is lifted up on the mountains, look; and when the trumpet is blown, listen

See how you translated "signal" in Isaiah 5:26. AT: "pay attention when you see the signal flag on the mountains and when you hear the sound of the trumpet." (See: rc://en/ta/man/translate/figs-activepassive)
