eze 43:2JEHOVAH'S RETURN TO THE TEMPLE. (Eze. 43:1-27)
the way of the east--the way whereby the glory had departed (Eze 11:22-23), and rested on Mount Olivet (compare Zac 14:4).
his voice . . . like . . . many waters--So English Version rightly, as in Eze 1:24, "voice of the Almighty"; Rev 1:15; Rev 14:2, prove this. Not as FAIRBAIRN translates, "its noise."
earth his glory-- (Rev 18:1).
eze 43:3when I came to destroy the city--that is, to pronounce God's word for its destruction. So completely did the prophets identify themselves with Him in whose name they spake.
eze 43:6the man--who had been measuring the buildings (Eze 40:3).
eze 43:7the place--that is, "behold the place of My throne"--the place on which your thoughts have so much dwelt (Isa 2:1-3; Jer 3:17; Zac 14:16-20; Mal 3:1). God from the first claimed to be their King politically as well as religiously: and He had resisted their wish to have a human king, as implying a rejection of Him as the proper Head of the state. Even when He yielded to their wish, it was with a protest against their king ruling except as His vicegerent. When Messiah shall reign at Jerusalem, He shall then first realize the original idea of the theocracy, with its at once divine and human king reigning in righteousness over a people all righteous (Eze 43:12; Isa 52:1; Isa 54:13; Isa 60:21).
eze 43:9carcasses of their kings--It is supposed that some of their idolatrous kings were buried within the bounds of Solomon's temple [HENDERSON]. Rather, "the carcasses of their idols," here called "kings," as having had lordship over them in past times (Isa 26:13); but henceforth Jehovah, alone their rightful lord, shall be their king, and the idols that had been their "king" would appear but as "carcasses." Hence these defunct kings are associated with the "high places" in Eze 43:7 [FAIRBAIRN] Lev 26:30 and Jer 16:18, confirm this. Manasseh had built altars in the courts of the temple to the host of heaven (Kg2 21:5; Kg2 23:6).
I will dwell in the midst . . . for ever-- (Rev 21:3).
eze 43:10show the house . . . that they may be ashamed of their iniquities--When the spirituality of the Christian scheme is shown to men by the Holy Ghost, it makes them "ashamed of their iniquities."
eze 43:12whole . . . most holy--This superlative, which had been used exclusively of the holy of holies (Exo 26:34), was now to characterize the entire building. This all-pervading sanctity was to be "the law of the (whole) house," as distinguished from the Levitical law, which confined the peculiar sanctity to a single apartment of it.
eze 43:13As to the altar of burnt offering, which was the appointed means of access to God.
eze 43:15altar--Hebrew, Harel, that is, "mount of God"; denoting the high security to be imparted by it to the restored Israel. It was a high place, but a high place of God, not of idols.
from the altar--literally, "the lion of God," Ariel (in Isa 29:1, "Ariel" is applied to Jerusalem). MENOCHIUS supposes that on it four animals were carved; the lion perhaps was the uppermost, whence the horns were made to issue. GESENIUS regards the two words as expressing the "hearth" or fireplace of the altar.
eze 43:16square in the four squares--square on the four sides of its squares [FAIRBAIRN].
eze 43:17settle--ledge [FAIRBAIRN].
stairs--rather, "the ascent," as "steps" up to God's altar were forbidden in Exo 20:26.
eze 43:18The sacrifices here are not mere commemorative, but propitiatory ones. The expressions, "blood" (Eze 43:18), and "for a sin offering (Eze 43:19, Eze 43:21-22), prove this. In the literal sense they can only apply to the second temple. Under the Christian dispensation they would directly oppose the doctrine taught in Heb. 10:1-18, namely, that Christ has by one offering for ever atoned for sin. However, it is possible that they might exist with a retrospective reference to Christ's sufferings, as the Levitical sacrifices had a prospective reference to them; not propitiatory in themselves, but memorials to keep up the remembrance of His propitiatory sufferings, which form the foundation of His kingdom, lest they should be lost sight of in the glory of that kingdom [DE BURGH]. The particularity of the directions make it unlikely that they are to be understood in a merely vague spiritual sense.
eze 43:20cleanse--literally, "make expiation for."
eze 43:21burn it . . . without the sanctuary-- (Heb 13:11).
eze 43:26Seven days--referring to the original directions of Moses for seven days' purification services of the altar (Exo 29:37).
consecrate themselves--literally, "fill their hands," namely, with offerings; referring to the mode of consecrating a priest (Exo 29:24, Exo 29:35).
eze 43:27I will accept you-- (Eze 20:40-41; Rom 12:1; Pe1 2:5).
