Exodus 33:3

I will not go up in the midst of thee By my own special and gracious presence, as hitherto I have done, but I will depart from thee. In pursuance hereof, God removes his tabernacle without the camp. I will only make good my promise to thy fathers, and send an angel to accomplish it, but I will show no particular and further kindness to thee. Lest I consume thee in the way Lest thy sins should be aggravated by my presence and favour, and thereby I should be provoked utterly to destroy thee. So God shows that their perverseness makes this severity necessary for them, and that he, even in his judgment, remembers mercy to them.
