Genesis 9:21

9:21 When he drank some of the wine, he got drunk and uncovered himself inside his tent.

tn The Hebrew verb גָּלָה (galah) in the Hitpael verbal stem (וַיִּתְגַּל, vayyitggal) means “to uncover oneself” or “to be uncovered.” Noah became overheated because of the wine and uncovered himself in the tent.
