נִיחֹחַnichoach meaning in Biblical Hebrew
soothing aroma (of a sacrifice) · noun, masculine
Also spelled in English: nihoah, nichoah

The whole point of the smoke going up was that God would breathe it in and calm down. That is what the word actually says.
וַיָּרַח יְהוָה אֶת־רֵיחַ הַנִּיחֹחַ
“And the LORD smelled the soothing aroma. (Genesis 8:21)”
Consider whether the image of God inhaling smoke and settling is comforting or uncomfortable for you.
