“Even your kinsfolk,
Even your own family,
Even they have dealt treacherously
They are in full cry after you.
Do not believe them,
Even if they speak
Friendly words to you.”
This verse is not in the Jerusalem Bible. I do not know why. Yahweh seems to warn Jeremiah that he should be careful with his own family and relatives. They have dealt treacherously with him. They were in full throat after him. He was not to believe anything that they said to him, even if it was friendly words.
