He caused their chariot wheels to swerve, and He made them drive with difficulty; so the Egyptians said, 'Let us flee from Israel, for the LORD is fighting for them against the Egyptians.'
(New American Standard Bible)
And took off their chariot wheels, that they drave them heavily: so that the Egyptians said, Let us flee from the face of Israel; for the LORD fighteth for them against the Egyptians.
(King James Version)
