Jeremiah 34:11

But afterward they turned, they changed their minds, and caused the servants and the handmaids whom they had let go free to return and brought them into subjection for servants and for handmaids. When the Chaldean invasion was upon them, they pretended a meek submission under the will of the Lord, but when the danger seemed to be past, at the temporary withdrawal of the invading army, they once more brought their servants under the yoke, thus proving that their conversion was not sincere. Like the hypocrites of our day they feigned submission in order to gain their end.
