Jeremiah 12:5-6

5If thou hast run with footmen, and they have wearied thee, how wilt thou then contend with horses? And if in a land of peace thou thinkest thyself in security, how wilt thou then do in the swelling of the Jordan?

6For even thy brethren, and the house of thy father, even they have dealt treacherously with thee, even they have cried aloud after thee. Believe them not, though they speak good [words] unto thee.
