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

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

Then he flung down his staff and it became a serpent manifest,

So he cast down his rod, and lo! it was an obvious serpent;

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