One of God’s key characteristics is the reliability of his word. Jeremiah frequently used the phrase “thus saith the LORD” to indicate God’s authority over what he said. As in the creation of the world, God speaks things into being and can cause something to happen by merely saying that it will. Therefore, God only says things that are consistent with his will. God does everything he promises to, because to him, saying and doing are essentially the same thing.

The commandments that were given to the Israelites were like a contract between God and his people that bound their actions together so that an obligation existed whenever obedience or disobedience occurred. If the Israelites kept the commandments, God rewarded them, and if they didn’t, he punished them. So, over time, the Israelites learned how to get what they wanted from God.

Zedekiah, the last king of Judah, was told to become a servant to Nebuchadnezzar, king of Babylon (Jeremiah 25:11). Instead of submitting himself to Nebuchadnezzar’s authority, Zedekiah continually resisted and fought against going into captivity. In his attempt to change the outcome of his situation, Zedekiah used one of God’s commandments to manipulate God’s behavior. Zedekiah made a covenant with all the people in Jerusalem to let their Hebrew slaves go free (Jeremiah 34:8-9).

Zedekiah’s interpretation of the law was correct in that he understood it was wrong for the Israelites to make slaves of their own people, but the law of liberty or year of jubilee did not mean that letting the people go free would prevent Judah from going into captivity. And yet, God recognized Zedekiah’s  action and told him, “And ye were now turned, and had done right in my sight, in proclaiming liberty every man to his neighbor” (Jeremiah 34:15).

Unfortunately, Zedekiah wasn’t sincere in his effort to follow God’s commandment. When he saw that Pharaoh’s army was coming from Egypt, Nebuchadnezzar’s army stopped attacking Jerusalem (Jeremiah 37:5). And so, it says in Jeremiah 34:11, “But afterwards they turned, and caused the servants and the handmaids whom they had let go free, to return, and brought them into subjection for servants and handmaids.”

As soon as Zedekiah thought he got what he wanted, Nebuchadnezzar stopped attacking Jerusalem, he did an about face and recanted his promise to let the Hebrew slaves go free. God responded to Zedekiah’s broken promise by sending Nebuchadnezzar’s army back. He told Zedekiah, “Behold, I will command, saith the LORD, and cause them to return to this city; and they shall fight against it, and take it, and burn it with fire: and I will make the cities of Judah a desolation without an inhabitant” (Jeremiah 34:22).
