Jeremiah 12:5 in the King James Version
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?
Context
4 How long will the land mourn, and the herbs of the whole country wither? Because of the wickedness of those who dwell therein, the animals and birds are consumed; because they said, “He won’t see our latter end.”
5 “If you have run with the footmen, and they have wearied you, then how can you contend with horses? Though in a land of peace you are secure, yet how will you do in the pride of the Jordan?
6 For even your brothers, and the house of your father, even they have dealt treacherously with you! Even they have cried aloud after you! Don’t believe them, though they speak beautiful words to you.
