Jeremiah 12:5-6

5If 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 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 fair words unto thee.
