I said to them, “We according to our ability have redeemed our Jewish brothers who were sold to the nations; now would you even sell your brothers that they may be sold to us?” Then they were silent and could not find a word to say. [Nehemiah 5:8]
The 5th chapter of the book of Nehemiah recorded Jews under oppression approaching Nehemiah for help. Among them was a group who were forced to sell their children to slavery due to debts, and they were seeking help to redeem their children. Nehemiah was vey angry when he heard their cases. He spoke to the nobles and rulers, and managed to get them to free the slaves and restore to the oppressed their properties. The verse above reveals that Nehemiah had been redeeming Jews who were sold as slaves to foreign nations, thus he was angry that the Jewish nobles and rulers were selling their Jewish brothers to slavery.
This passage points to Christ. People dwelling in sin are slaves to sin, and only Christ has the power to redeem them and free them from the bondage of sin, just like Nehemiah redeeming his people from slavery. When we are in difficult times, we can cry out to Jesus and He will not ignore our pleas, just like Nehemiah taking up the case for the oppressed.
