Jeremiah 12:5-6

5“If you have run with the footmen, and they have wearied you, Then how can you contend with horses? And if in the land of peace, In which you trusted, they wearied you, Then how will you do in the floodplain of the Jordan?

6For even your brothers, the house of your father, Even they have dealt treacherously with you; Yes, they have called a multitude after you. Do not believe them, Even though they speak smooth words to you.
