The word Ketoret comes from the word קטר which means connection or a knot in Aramaic.
Proverbs 27:9
“שֶׁמֶן וּקְטֹרֶת יְשַׂמַּח לֵב וּמֶתֶק רֵעֵהוּ מֵעֲצַת נָפֶשׁ.”
“Oil and perfume (Ketoret, Incense) delight the heart, And the sweetness of a man’s friend gives delight by hearty counsel.”
The High Priest burnt the Ketoret in the Holy Temple, It created a straight column up to heavens as far as the eye can see. The column of smoke was not affected by weather conditions like wind or rain.
