The Hebrew verb qatar (Χ§ΦΈΧΦ·Χ¨) means to burn incense, to cause to go up in smoke, to make offerings ascend as a pleasing aroma. It is the standard term for the sacrificial burning of incense and burnt offerings throughout the Levitical system, describing the act of causing the smoke to rise toward God as an act of worship and propitiation.
Incense-burning (qatar) in Israel's worship carried rich theological meaning: (1) Ascension β the smoke rises upward, symbolizing prayer ascending to heaven (Psalm 141:2; Revelation 5:8). (2) Aroma β the pleasing scent indicates the offering is accepted. (3) Mediation β the High Priest burned incense in the Holy Place twice daily, his mediation separating the people from God's holiness.
The danger of unauthorized qatar was severe β Nadab and Abihu died offering "strange fire" (Leviticus 10:1). Unauthorized worship is not accepted worship. The NT fulfillment is Christ as both our High Priest and our incense offering β His intercession (Hebrews 7:25) is the eternal qatar that ascends before the Father on our behalf, always accepted, never extinguished.
