Deuteronomy 13:1

13:1 Suppose a prophet or one who foretells by dreams should appear among you and show you a sign or wonder,

Deuteronomy 13:9

13:9 Instead, you must kill him without fail! Your own hand must be the first to strike him, and then the hands of the whole community.

tn Heb “or a dreamer of dreams” (so KJV, ASV, NASB). The difference between a prophet (נָבִיא, navi’) and one who foretells by dreams (חֹלֵם אוֹ, ’o kholem) was not so much one of office – for both received revelation by dreams (cf. Num 12:6) – as it was of function or emphasis. The prophet was more a proclaimer and interpreter of revelation whereas the one who foretold by dreams was a receiver of revelation. In later times the role of the one who foretold by dreams was abused and thus denigrated as compared to that of the prophet (cf. Jer 23:28).

tn The expression אוֹת אוֹ מוֹפֵת (’oto mofet) became a formulaic way of speaking of ways of authenticating prophetic messages or other works of God (cf. Deut 28:46; Isa 20:3). The NT equivalent is the Greek term σημεῖον (shmeion), a sign performed (used frequently in the Gospel of John, cf. 2:11, 18; 20:30-31). They could, however, be counterfeited or (as here) permitted to false prophets by the Lord as a means of testing his people.

tn The Hebrew text uses the infinitive absolute for emphasis, which the translation indicates with the words “without fail” (cf. NIV “you must certainly put him to death”).

tn Heb “to put him to death,” but this is misleading in English for such an action would leave nothing for the others to do.
