Exo Exodus, chapter Book of Exodus, chapter 23
Yahweh gave the Israeli people several promises
“Note this: I am going to send an angel ahead of you, to guard you as you travel and to bring you safely to the place that I have prepared for you. Pay attention to what he says and obey him. Do not rebel against him, because he will have my authority [MTY] and he will ◄punish/not forgive► [LIT] you if you rebel against him.
