Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible;

Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)!

Then he flung down his staff and lo! it was a serpent manifest;

So he threw his rod, then lo! it was a serpent manifest,

So Moses threw his staff, and suddenly it was a serpent, manifest.
