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 (’ot ’o 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 (sēmeion), 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.
