The incense altar was the small gold-overlaid altar (one cubit square, two cubits high) that stood in the Holy Place of the tabernacle, just before the veil of the Most Holy (Exodus 30:1-10; 37:25-28). Twice daily — morning and evening — the priest burned a specially compounded incense of stacte, onycha, galbanum, and pure frankincense (Exodus 30:34-38) on its surface. The smoke was a continual, fragrant symbol of the people’s prayers ascending to God (Psalm 141:2; Revelation 5:8; 8:3-4). Strange fire on this altar killed Nadab and Abihu (Leviticus 10:1-2). Christ Himself is now our incense altar — His prayers continually ascend on behalf of the saints (Hebrews 7:25).
(Composite.) The altar of incense; the smaller altar before the veil, on which sweet spices were burned.
Webster: incense — “perfume exhaled by fire; the odors of spices and gums, burnt in religious rites, or as an offering to some deity.”
The incense altar of the tabernacle and temple was distinct from the larger bronze altar of burnt offering: it stood inside the Holy Place, was overlaid with gold, and received only the daily incense and the blood of the sin-offering on the Day of Atonement.
Exodus 30:1 — "And thou shalt make an altar to burn incense upon: of shittim wood shalt thou make it."
Exodus 30:7 — "And Aaron shall burn thereon sweet incense every morning... And when Aaron lighteth the lamps at even, he shall burn incense upon it, a perpetual incense before the LORD."
Psalm 141:2 — "Let my prayer be set forth before thee as incense; and the lifting up of my hands as the evening sacrifice."
Revelation 8:3 — "And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints."
Prayer has been demoted to private wishful thinking; the picture of prayer as fragrant smoke before God's throne is forgotten.
Scripture is consistent: prayer is incense (Psalm 141:2; Revelation 5:8; 8:3-4). It is offered, it ascends, it pleases God by its fragrance, and it has weight in heaven. The incense altar made this picture daily and visible to Israel for a thousand years.
Modern prayer is often imagined as a private brain activity that may or may not be heard. The incense altar corrects that: prayer is liturgical, fragrant, and continual. It is not merely sent — it is offered, on an altar, by a priest, before a God who delights in the smell.
Hebrew names both the small altar and the substance burned upon it.
H4289 — מַחְתָּה (machtah) — censer, fire-pan; the implement that carried coals from the burnt-offering altar to the incense altar.
H7004 — קְּטֹרֶת (qetoreth) — the compounded incense itself; sweet smoke offered before the LORD.
"Prayer is incense; treat it like an offering, not a tweet."
"The morning prayer and the evening prayer are the household's incense altar."
"If the smoke does not rise daily, the household is not yet a temple."
