23 If the river rages, it is not disturbed, it is secure, though the Jordan should surge up to its mouth.
Darby
23 Lo, the river overfloweth he startleth not: he is confident though a Jordan break forth against his mouth.
KJV
23 Behold, he drinketh up a river, [and] hasteth not: he trusteth that he can draw up Jordan into his mouth.
