Matthew Poole's Concise Commentary
1 Kings 6:20
In the forepart, or rather, which was in the inner part, to wit, of the house; called here in Hebrew, the forepart, not because a man first enters there, but because when a man is entering, or newly entered, into the house, it is still before him. Thus the same, or the like word proceeding from the same root, is oft used, as Leviticus 10:18 1 Kings 6:19,29,30,36 1 Chronicles 28:11. Twenty cubits in the height thereof. Object. The great house was thirty cubits high, above, 1 Kings 6:2. Answ. It is probably affirmed by divers, that the most holy place was not so high as the holy place by ten cubits; which was no way inconvenient, nor against the rules of proportion observed in buildings. And as the second part of the building was far lower than the first, which was the porch; so the third part might be considerably lower than the second. And it might be lower either,
1. Outwardly, or in respect of the walls of it, which might be only twenty cubits high, and at that height covered with a flat roof; it being but decent that that eminently holy place should be distinguished from the less holy, even by its outward and visible shape. Or,
2. Inwardly, or within the walls of that part. For although this part might be vaulted at the top, as the holy place was, which vaulted roof some think was ten cubits high; yet here might be the difference, that the vaulted roof of the holy place lay open to view, whereas that of the most holy was covered with a flat roof from wall to wall, at the height of twenty cubits. So covered, i.e. with gold, 1 Kings 7:48 1 Chronicles 28:18. The altar, to wit, the altar of incense, which was put next to the most high place, 1 Kings 6:22. Which was of cedar. Object. This altar was made of shittim wood, Exodus 30:1. Answ. Either that was covered with cedar, that it might be agreeable to the rest; all being cedar, as was said, 1 Kings 6:18. Or this was a new altar which Solomon made by Divine command and direction, delivered to him, either immediately, or by his father; of which see 1 Chronicles 28:12, &c. But this place may seem to be better translated thus, and he covered the altar with cedar; either to make it like the rest; or because this was a new altar made of stone, and therefore fit to be covered with cedar, that it might better receive and retain the gold wherewith this cedar was overlaid, 1 Kings 6:22.
