Midrash sur La Genèse 9:8

(Gen. 39:2, cont.:) AND HE WAS A SUCCESSFUL MAN. He used to gird up his loins; and, when his master would say to him: Pour me a glass of water, he would pour it. < Then he would say > : Give me cold < water >, and he would give it to him out of the same vessel. When his master would say to him: Give me wine, he would give it to him. < Then he would say >: Give it to me tripled (i.e., mixed with two parts of water).⁵¹So Buber, p. 186, n. 66. He would give it to him, and it would become sweet by itself.⁵²Cf. Tanh., Gen. 9:8; Gen. R. 86:5. It is therefore stated (in Gen. 39:2, cont.): AND HE WAS A SUCCESSFUL MAN.

"And God said to Noah and to his sons with him "I now establish My covenant with you and your offspring to come" (Genesis 9:8-9)": Rabbi Judah and Rabbi Nehemiah: Rabbi Judah said: "Because he transgressed my command and because of that was despised". And Rabbi Nehemiah said: "He added to my command and acted in holiness. Because of that he and his sons obtained the speech: "And God said to Noah and to his sons with him".
