American Standard Version (ASV):
If thou hast run with the footmen, and they have wearied thee, then how canst thou contend with horses? and though in a land of peace thou art secure, yet how wilt thou do in the pride of the Jordan?
King James Version (KJV):
If thou hast run with the footmen, and they have wearied thee, then how canst thou contend with horses? and [if] in the land of peace, [wherein] thou trustedst, [they wearied thee], then how wilt thou do in the swelling of Jordan?
