Midrash su Esodo 6:13

1) "And He called to Moses and the L–rd spoke to him, etc." "to him" — to exclude Aaron. R. Yehudah b. Betheira said: Thirteen dibroth (accompanied by a command) were stated in the Torah to Moses and Aaron, and, corresponding to them, thirteen limitations, to teach us that they were not spoken to Aaron, but to Moses, to tell them to Aaron. (The dibroth: 1) [Shemoth 6:13]; 2) [Shemoth 7:8]; 3) [Shemoth 9:8]; 4) [Shemoth 12:1]; 5) [Shemoth 12:43]; 6) [Vayikra 11:1]; 7) [Vayikra 13:1]; 8) [Vayikra 14:33]; 9 [Vayikra 15:1]; 10 [Bamidbar 2:1]; 11 [Bamidbar 4:1]; 12 [Bamidbar 4:18]; 13) [Bamidbar 19:2].)

He commanded them, saying; “Thus shall you say unto my lord Esau” (Gen. 32:5). R. Judah the son of Simon began the discussion with the verse: As a troubled fountain, and a corrupted spring, so is a righteous man that giveth way before the wicked (Prov. 25:26). That is to say, the righteous man is like a troubled fountain and a corrupted spring when he demeans himself before the wicked. Thus shall you say unto my lord Esau. Jacob called Esau my lord, for the Torah teaches that one must be respectful toward the government (those in power). R. Ishmael said: Observe that Scripture says: And the Lord spoke unto Moses and unto Aaron, and gave them a charge unto the children of Israel and unto Pharaoh, king of Egypt (Exod. 6:13).⁴God refers to Pharaoh as king to demonstrate the duty to honor the one in power. He did so to teach them to be respectful toward the government (those in power).

(Deut. 14:22:) YOU SHALL SURELY TITHE. This text is related (to Prov. 28:22): AN EVIL-EYED PERSON (i.e., a miser) MOVES QUICKLY AFTER WEALTH; AND HE DOES NOT KNOW <THAT POVERTY WILL COME TO HIM>. R. Hanina interpreted the Scripture verse with reference to Ephron (of Gen. 23),⁷Above, Tanh. (Buber), Exod. 6:5; Lev. 9:1; Tanh, Deut. 4:10; Gen. R. 58:7; Exod. R. 31:17; PRK 10:1; see also BM 87a. Cf. above, Tanh. (Buber), Exod. 6:13, which identifies the man with Cain. for Rabbi Hanina said: All the shekels mentioned in the Torah are sela's, those in the Prophets are litrai,⁸The Greek word means “pounds.” and those in the Writings are centenarii,⁹The Latin word denotes weights of a hundred pounds. except for the shekels of Ephron, which are not centenarii.¹⁰For this valuation of the shekel, see yQid. 1:3 (59d), 5 (60c); Bekh. 50a; PR 1:4. This is what is written (in Gen. 23:9): LET HIM GIVE IT TO ME AT THE FULL PRICE. Because he brought the evil eye (of greed) for Abraham's wealth, the written text lacks the letter waw.
