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.

13. The last year of Zedekiah was the sabbatical year. How just the retribution, that they who, against God's law and their own covenant, enslaved their brethren, should be doomed to bondage themselves: and that the bond-servants should enjoy the sabbatical freedom at the hands of the foe (Jer 52:16) which their own countrymen denied them!
