Deuteronomy 18 deals with three subject matters and can be divided into three sections: Levitical priesthood in Israel (vv. 1-8), superstitious practices (vv. 9-14) and prophecy (vv. 15-22). In the first section, Moses instructs the Israelites on how to provide for the Levitical priests who minister before the LORD at the central sanctuary. As ministers, the Levitical priests are not supposed to do any secular job. They are to depend solely upon the dues of the other tribes. In the second section, Moses forbids the Israelites from following the detestable practices of the surrounding nations in order to live blamelessly before the Suzerain (Ruler) God in the Promised Land. In the last section, Moses commands the Israelites to reject the sorcery and witchcraft of the surrounding nations, and instead to listen to God through godly prophets.
Deuteronomy 18 can be outlined as follows:
-Concerning the Priests and Levites (Deut. 18:1 – 8)
-Concerning Prophets (Deut. 18:9 – 22)
—Illegitimate Practices of Prophets (Deut. 18:9 – 14)
—Legitimate Practices of Prophets (Deut. 18:15 – 22)

Deuteronomy 18:1-8

Since the Levitical priests would minister before the LORD at the central sanctuary, they were not supposed to do any secular job. They were to depend upon the dues and offerings of the other tribes.

Deuteronomy 18:9-14

Moses discussed religious practices that are prohibited. He then described the office of prophets who proclaimed the word of their LORD.

Deuteronomy 18:15-22

Moses then told the Israelites that after his death, the LORD would raise up prophets like himself. The people were to turn to these godly prophets for communication with God. God also predicts Jesus will be a prophet like Moses.
