Deuteronomy 18:15

a Prophet from among you of your brethren like unto me, with the Holy Spirit will the Lord your God raise up unto you; to Him shall you be obedient.

such as I i.e., a prophet of God , and not a soothsayer.

PROPHET WILL THE ETERNAL THY G-D RAISE UP UNTO THEE, FROM THE MIDST OF THEE, OF THY BRETHREN, LIKE UNTO ME. The purport of the expression from the midst of thee is to allude that prophecy is present only in the Land of Israel.. It is for this reason that Scripture speaks with reference to the Land in this term — The burden concerning the valley of ‘chizayon’ (vision), and as our Rabbis have mentioned. A similar meaning is conveyed by the expression of thy brethren, that G-d has granted you eminence over all peoples and He will put His spirit only upon you. “Like unto me, for I am from the midst of thy brethren. in the same degree of prophecy, for the Torah has already testified, And there hath not arisen a prophet since in Israel like unto Moses (further, 34:10). The comparison means, therefore, “just as I am an Israelite etc.” (Mizrachi). — He will raise up unto thee in my stead, and so likewise from prophet to prophet.” And Rabbi Abraham ibn Ezra commented: “Like unto me, who am a prophet of G-d, and not a diviner [by clouds], nor any [other] diviner.”
It is possible that the expression from the midst of thee means that you can trust his words since he is from your brethren, from the midst of thee. Similarly, in my opinion, like unto me means that he will be established to be a prophet of the Eternal and you will believe in him just as you believe in me. I will yet explain this.

נביא מקרבך מאחיך כמוני, such prophets establish the authentic nature of their mission by commanding you to observe the laws of the Torah, not like false prophets or dreamers purporting to have been told that you should practice some idolatrous rites. When the Torah wrote in Deut. 34,10 that there never again arose a prophet of the stature of Moses, what is meant is the manner in which Moses was familiar with G’d on an unprecedented level, speaking to Him at any time, and being addressed by Him without introductory formalities, i.e. פנים אל פנים, “face to face,” as the informal nature of two friends speaking with one another. The verse does not mean that subsequent prophets would have less faith in G’d than Moses had had. Concerning that aspect of Moses as a prophet, he told the people that prophets after him would display similar faith in the Lord, i.e. כמוני. They too would faithfully deliver messages from G’d, neither withholding part nor adding something of their own and passing it off as a Divine message.

אליו תשמעון, if his instructions which appear to deviate from Jewish norms are meant as a temporary measure, addressing a specific emergency.
