Jeremiah 38:8

It now follows, that Ebed-melech went forth from the palace and came to the king’s tribunal, that he might there plead the cause of the Prophet. It is right to notice this circumstance as well as the former. For if Ebedmelech had met the king accidentally, he might have spoken to him in passing; but as he went forth from the palace, it is clear that he had been meditating on what he was going to do, and that he had not felt only a sudden impulse of compassion: but that when he might have rested quietly in the palace, he came of his own accord to the king to make known his complaint. And further, he did not address the king in a room or in some private corner of the palace, but he spoke to him in the gate, that is, in a public assembly. We hence see that the previous circumstance commends to us the perseverance of this man, for he was not only suddenly moved, but persevered in his holy purpose; and the second circumstance commends to us his magnanimity, for he did not shun ill-will, but openly and boldly spoke for Jeremiah before the people; and he amplified the excellency of the Prophet by bringing an accusation against the princes. He no doubt knew that he was bringing himself into danger, but he exposed his own life that he might aid the Prophet.
