Jeremiah 34:15

Ye had made a covenant before me in the house which is called by my name. — The words point to the solemnity with which the new engagements had been contracted. It was not merely that the king had issued an edict, or that judges had given their decisions in accordance with the old law, but princes and people had met together in the courts of the Temple, and there, in the presence of Jehovah, had entered into this covenant, as did their descendants afterwards in the days of Nehemiah (Nehemiah 5:12), with Him and with each other. Their sin in breaking their covenant was therefore a sin against Him as well as against their brethren.
