'Fragrant Incense' in the Bible

For we [i.e., through our preaching] are like a fragrant incense which goes up to God, [and spreads the knowledge] of Christ among both saved and lost people.

You have paid me in full, and more too. I am fully supplied with what I have received from you through Epaphroditus. It is like fragrant incense, just such a sacrifice as God welcomes and approves.
