Éxodo 30:10

10 »Una vez al año, Aarón deberá purificar
el altar untando los cuernos con sangre de la ofrenda que se hace para purificar al pueblo de su pecado. Esta ceremonia se llevará a cabo todos los años, de generación en generación, porque ese altar es el más santo del Señor

Éxodo 30:10 Meaning and Commentary

Exodus 30:10

And Aaron shall make an atonement upon the horns of it once in
a year
On the day of atonement, as the Targum of Jonathan, and so Jarchi and Aben Ezra explain it; and the atonement here referred to seems to be an atonement for the altar itself, see ( Leviticus 16:18 Leviticus 16:19 ) and as the altar of burnt offering was first expiated and then used, ( Exodus 29:36 Exodus 29:37 ) so it seems the altar of incense had not only an atonement made on it, but for it: and this was done

with the blood of the sin offering of atonement;
by sprinkling the blood of that offering upon the horns of it, as we learn from the afore mentioned place; and this shows that Christ's mediation and intercession is founded upon the virtue of his blood, and the efficacy of his atoning sacrifice, see ( 1 John 2:1 1 John 2:2 )

once in the year shall he make atonement upon it, throughout your
generations;
which proves the insufficiency of all legal sacrifices of themselves to take away sin, since every year, as the apostle observes, there was a remembrance of it, ( Hebrews 10:3 Hebrews 10:4 )

it is most holy unto the Lord;
either the atonement made on the day of atonement, which was a most holy part of service, and pointed at the great atonement made by the most Holy One, the Son of God; or this altar thus expiated, and devoted to sacred use, was reckoned a most sacred one to the Lord, and so was to have nothing offered upon it but what he ordered; with which Jarchi agrees in his note,

``the altar is sanctified to these things only, and not to any other service.''

8 Y cada tarde, cuando encienda las lámparas, también quemará incienso en presencia del Señor

10 »Una vez al año, Aarón deberá purificar
el altar untando los cuernos con sangre de la ofrenda que se hace para purificar al pueblo de su pecado. Esta ceremonia se llevará a cabo todos los años, de generación en generación, porque ese altar es el más santo del Señor

Entonces el Señor
le dijo a Moisés:

12 «Cada vez que hagas un censo del pueblo de Israel, cada hombre contado tendrá que pagar al Señor
un rescate por sí mismo. Así ninguna plaga herirá a los israelitas cuando los cuentes.
