SEV Biblia, Chapter 16:39
Y el sacerdote Eleazar tomó los incensarios de metal con que los quemados habían ofrecido; y los extendieron para cubrir el altar,
John Gill's Bible Commentary
Ver. 39. And Eleazar the priest took the brazen censers , etc.] The metal of which these censers were made is particularly observed, to show that they were fit for the use they were ordered to be put unto, namely, for a covering of the altar of burnt offering, which was covered with brass, that being very suitable, since fire was continually burning on it; and by this it appears that these censers were different from those of Aaron and his sons, for theirs were silver ones; the high priest on the day of atonement indeed made use of golden one, but at all other times he used a silver one f237 ; and so did the common priests every day, morning and night, when they offered incense f238 , wherewith they that were burnt had offered ; the two hundred fifty men burnt with fire from the Lord, having offered incense to him with the brazen censers: and they were made broad [plates for] a covering of the altar ; not by Eleazar, but by workmen skilled in the art of drawing or beating any kind of metal into thin plates, by the direction and order of Eleazar.
Matthew Henry Commentary
Verses 35-40 - A fire went out from the Lord, and consumed the two hundred and fift men that offered incense, while Aaron, who stood with them, wa preserved alive. God is jealous of the honour of his own institutions and will not have them invaded. The sacrifice of the wicked is a abomination to the Lord. The censers are devoted, and, as all devote things, must be made serviceable to the glory of God. This covering of the altar would remind the children of Israel of this event, tha others might hear and fear, and do no more presumptuously. They brough destruction on themselves both in body and soul. Thus all who break the law and neglect the gospel choose and love death.
