Pay attention to him and listen to his voice; do not defy him, for he will not forgive your rebellion — my name is in him.
In context
19Bring the best of the firstfruits of your soil to the house of Yahweh your God. Do not cook a young goat in its mother’s milk. 20See, I am sending an angel ahead of you, to guard you on the way and to bring you to the place I have prepared. 21Pay attention to him and listen to his voice; do not defy him, for he will not forgive your rebellion — my name is in him. 22But if you truly listen to his voice and do everything I say, I will be an enemy to your enemies and a foe to your foes. 23My angel will go ahead of you and bring you to the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites, and the Jebusites, and I will wipe them out.
