Dan will be a serpent on the way, A horned snake on the path, Which biteth the horse's heels, So that the rider falleth backwards.

Then sang Moses and the children of Israel this song to Jehovah, and spoke, saying, I will sing unto Jehovah, for he is highly exalted: The horse and his rider hath he thrown into the sea.

And Miriam answered them, Sing to Jehovah, for he is highly exalted: The horse and his rider hath he thrown into the sea.

What time she lasheth herself on high, she scorneth the horse and his rider.

and with thee I will break in pieces the horse and his rider; and with thee I will break in pieces the chariot and its driver;

In that day, saith Jehovah, I will smite every horse with astonishment, and his rider with madness; but I will open mine eyes upon the house of Judah, and will smite every horse of the peoples with blindness.
