Midrash sur Zacharie 3:8

When Pharaoh shall speak unto you, saying: “Show a wonder for you” (Exod. 7:9). He will be making a reasonable request to you. You find in the case of Noah, that though He said to him, after He saved him from the flood, Neither shall there be anymore a flood (Gen. 9:11), Noah demanded a sign, and God assured him: I have set my bow in the cloud (ibid., v. 13). Similarly, when Hezekiah was sick, the Holy One, blessed be He, sent Isaiah to him and he said: Thus saith the Lord, the God of David, thy father: “I have heard thy prayer, I have seen thy tears; behold, I will heal thee; on the third day thou shalt go up unto the house of the Lord” (II Kings 20:5). But he replied: What shall be the sign? (ibid., v. 8), and He answered: This shall be the sign unto thee from the Lord, that the Lord will do the thing that He hath spoken: shall the shadow go forward ten degrees, or go back ten degrees? (ibid., v. 9). Likewise, Joshua, the high priest, was told: Hear now, O Joshua the high priest, … for they are men that are a sign (Zech. 3:8). Since the righteous demanded signs, how much more did the wicked Pharaoh (have the right to do so). Hence, when Pharaoh says unto you: Show a wonder for you (he will be making a reasonable request).

(Fol. 13b) Our Rabbis were taught: If it happened that he, his teacher and his father were in captivity [and he was able to redeem only one] he himself has the preference over the teacher, and his teacher has the preference over his father. His mother, however, has the preference over all. A sage has the preference over a king of Israel, for if a sage dies, we have no equal to him, but if a king dies all Israel is fit for the throne. A king has the preference over a High-priest, as it is said (I Kings 1, 33) Take with you the servants of your lord. A High-priest has the preference over a prophet, as it is said (Ib.) And let Zadok the priest with Nathan the prophet, hence the priest precedes the prophet, and there is another passage (Zech. 3, 8) Hear now, O Joshua the High-priest, thou and thy fellows, etc. One might say that they were ignorants therefore the priest precedes them. The verse therefore says (Ib.) For they are men that are a sign (Mofeth). The word Mofeth is applied to prophecy, as it is said (Deut. 13, 2) And he gives thee a sign (Mofeth) or a wonder.
