Jeremiah 12:5-6

5“If you have run with footmen and they have tired you out, Then how can you compete with horses? If you fall down in a land of peace, How will you do in the 12thicket of the Jordan?6For even your 3brothers and the household of your father, Even they have dealt treacherously with you, Even they have cried aloud after you. Do not believe them, although they may say 4nice things to you.”
