I am confused as to the meaning of Exodus 23:25. The background is the following:
Now these are the judgments which thou shalt set before them. [God speaking]
Then in Exodus 23, God speaks about the famous angel with his name in him;
22 But if thou shalt indeed obey his voice, and do all that I speak; then I will be an enemy unto thine enemies, and an adversary unto thine adversaries. 23 For mine Angel shall go before thee, and bring thee in unto the Amorites, and the Hittites, and the Perizzites, and the Canaanites, the Hivites, and the Jebusites: and I will cut them off. 24 Thou shalt not bow down to their gods, nor serve them, nor do after their works: but thou shalt utterly overthrow them, and quite break down their images.
Then after this change of topic in verse 24, it seems to possibly go back to speaking about the angel, this is the key moment.
25 And ye shall serve the LORD your God, and he shall bless thy bread, and thy water; and I will take sickness away from the midst of thee.
Is this a simple change from the third person to the first person, or is there some reference to the angel here? If the former, why would this be spoken in this way? The interlinear is too complex for me to understand, and I am also not sure if the four-lettered name of God can be applied to the angel itself given that the name is in him.
