34:8-22 A Jew should not be held in servitude above seven years. This law they and their fathers had broken. And when there was some hope that the siege was raised, they forced the servants they had released into their services again. Those who think to cheat God by dissembled repentance and partial reformation, put the greatest cheat upon their own souls. This shows that liberty to sin, is really only liberty to have the sorest judgments. It is just with God to disappoint expectations of mercy, when we disappoint the expectations of duty. And when reformation springs only from terror, it is seldom lasting. Solemn vows thus entered into, profane the ordinances of God; and the most forward to bind themselves by appeals to God, are commonly most ready to break them. Let us look to our hearts, that our repentance may be real, and take care that the law of God regulates our conduct.But afterwards they turned,.... From the law of God, and their own agreement, and returned to their former usage of their servants; they changed their minds and measures. This seems to be done, when the king of Babylon, hearing the king of Egypt was coming to break up the siege of Jerusalem, quitted it, and went forth to meet him, as appears from Jeremiah 34:21; the Jews now finding themselves at liberty, and out of danger as they imagined, wickedly rebelled against the law of God; perfidiously broke their own covenant, repenting of what they had done, and returned to their former ways of oppression and cruelty; which shows they were not hearty and sincere in their covenant:

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; which was done by force, contrary to the will of their servants and handmaids, and in violation of the law of God, and their own solemn oath and covenant.
