עַד־מָתַ֗י הֲיֵ֛שׁ בְּלֵ֥ב הַנְּבִאִ֖ים נִבְּאֵ֣י הַשָּׁ֑קֶר וּנְבִיאֵ֖י תַּרְמִ֥ת לִבָּֽם׃
How long shall this be? Is it in the heart of the prophets that prophesy lies, And the prophets of the deceit of their own heart?
Rashi on Jeremiah
How long [will this be]? That they will prophesy falsely? Do these prophets who prophesy falsely have in their heart to execute their thoughts that they are thinking to cause My people to forget My name, etc.?
