Exodus 30:6-8

Amplified Bible

⁶ You shall put the altar of incense [in the Holy Place] in front and outside of the veil that screens the ark of the ^[a]Testimony, before the mercy seat that is over the Testimony, where I will meet with you. ⁷ Aaron shall burn sweet and fragrant incense on it; he shall burn it every morning when he trims and tends the lamps.^{(A) 8} When Aaron sets up the lamps at twilight, he shall burn incense, a perpetual incense before the Lord throughout your generations.
