אֹהֵ֣ב מ֭וּסָר אֹ֣הֵֽב דָּ֑עַת וְשֹׂנֵ֖א תוֹכַ֣חַת בָּֽעַר׃
Wer Wissen liebt, liebt Korrektur; Aber wer brutal ist, hasst Tadel.
Rashi
אך נח means NOAH ONLY. This is its real meaning. But the Midrashic explanation is (Midrash Tanchuma, Noach 9) that he was coughing and spitting blood because of the trouble he had with the cattle and beasts (אך is taken as a מיעוט limitation, meaning to say that something is defective); others say, that he was once late in bringing food to a lion, so it struck him. Regarding him may the words be applied (Proverbs 11:31), “Behold, even the righteous is paid (for his evil deeds) in this world’’.
