Deuteronomy 18:18

18 I shall raise to them a prophet, like thee, of the midst of their brethren, and I shall put my words in his mouth, and he shall speak to them all things, which I shall command to him. (I shall raise up for them a prophet, like thee, from the midst of their brothers, or of their kinsmen, and I shall put my words in his mouth, and he shall speak to them all the things, that I shall command to him.)

Deuteronomy 18:18 Meaning and Commentary

Deuteronomy 18:18

I will raise them up a prophet from among their brethren like
unto thee
So that it seems this promise or prophecy was first made at Mount Sinai, but now renewed and repeated, and which is nowhere else recorded; see ( Deuteronomy 18:15 ) when they were not only made easy for the present by appointing Moses to receive from the Lord all further notices of his mind and will, but were assured that when it was his pleasure to make a new revelation, or a further discovery of his mind and will, in future times, he would not do it in that terrible way he had delivered the law to them; but would raise up a person of their own flesh and blood, by whom it should be delivered, which was sufficient to prevent their fears for the future:

and will put my word in his mouth;
the doctrines of the Gospel, which come from God, and are the words of truth, faith, righteousness, peace, pardon, life, and salvation; and which Christ says were not his own, as man and Mediator, but his Father's, which he gave unto him, and put into his mouth, as what he should say, teach, and deliver to others; see ( John 7:16 ) ( 8:28 ) ( John 17:6 John 17:8 )

and he shall speak unto them all that I shall command him;
nor did he keep back, but faithfully declared the whole counsel of God; and as he gave him a commandment what he should say, and what he should speak, he was entirely obedient to it; see ( John 12:49 John 12:50 ) ( 15:15 ) .

Deuteronomy 18:18 In-Context

16 as thou askedest of thy Lord God in Horeb, when the company was gathered together, and thou saidest, I shall no more hear the voice of my Lord God, and I shall no more see this greatest fire, lest I die. (as thou askedest of the Lord thy God at Mount Sinai, when the congregation was gathered together, and thou saidest, We shall not hear again the voice of the Lord our God, and we shall not see this great fire again, lest we die.)

17 And the Lord said to me, They have spoken well all things (They have spoken all things well).

18 I shall raise to them a prophet, like thee, of the midst of their brethren, and I shall put my words in his mouth, and he shall speak to them all things, which I shall command to him. (I shall raise up for them a prophet, like thee, from the midst of their brothers, or of their kinsmen, and I shall put my words in his mouth, and he shall speak to them all the things, that I shall command to him.)

19 And I shall be venger of him, that will not hear his words, which he shall speak in my name. (And I shall take vengeance upon anyone, who shall not obey the words, which he shall speak in my name.)

20 Soothly a prophet shall be slain, which is depraved with pride, and will speak in my name those things, which I commanded not to him, that he should say, either by the name of alien gods. (And the prophet who is depraved with pride, and shall speak in my name those things, which I did not command him to say, or shall speak in the name of foreign, or other, gods, that prophet must be put to death.)
