Planting a vineyard

Hi,

And Noach, man of the earth, began and planted a vineyard.

וַיָּחֶל נֹחַ אִישׁ הָאֲדָמָה וַיִּטַּע כָּרֶם:

(Bereishit 9:20)

He made himself mundane, for he should have involved himself in another kind of planting first. 

עשה עצמו חולין, שהיה לו לעסוק תחלה בנטיעה אחרת:

 (Rashi to Bereishit 9:20)

Have a great day,

Mordechai
