Leviticus 6:13-15

Young's Literal Translation

¹³ fire is continually burning on the altar, it is not quenched.

¹⁴ `And this [is] a law of the present: sons of Aaron have brought it near before Jehovah unto the front of the altar,

¹⁵ and [one] hath lifted up of it with his hand from the flour of the present, and from its oil, and all the frankincense which [is] on the present, and hath made perfume on the altar, sweet fragrance -- its memorial to Jehovah.
