Exodus 30:7-8
7 And Aaron shall burn thereon sweet incensec every morning: when he dresseth the lamps, he shall burn incense upon it.
8 And when Aaron lightethd the lamps at even, he shall burn incense upon it, a perpetual incense before the LORD throughout your generations.
Exo. 30:7, 8. When the high priest lighted and dressed the lamp, then was he to burn incense on the golden altar of incense; signifying that the sweet and infinitely acceptable incense of Christ's merits was by the Holy Spirit signified by the lamp (see No. 475). It was by the eternal Spirit that Christ offered up himself without spot to God. It was by the Holy Spirit many ways. It was by the Holy Spirit that the human nature of Christ was united to the divine Logos, from which union arises the infinite value of his blood and righteousness. It was by the eternal Spirit that Christ performed righteousness. It was by the Spirit of God that Christ was perfectly holy, and performed perfect righteousness. It was by the Holy Spirit not only that his obedience was perfect, but performed with such transcendent love. It was by this Spirit that his sacrifice of himself was sanctified, being an offering to God in the pure and fervent flame of divine love which burnt in his heart, as well as in the flame of God's vindictive justice and wrath into which he was cast. And it was by this that his obedience and sacrifice were offered with such a love to his people, for whom he died, as implied a perfect union with them, whereby it was accepted for them.
