Melachim Alef 6:15

15 And he built the walls of the Beis [Hamikdash] within with boards of cedar, from the floor of the Beis [Hamikdash] to the rafters of the ceiling; and he covered them on the inside with wood, and covered the floor of the Beis [Hamikdash] with planks of cypress.

Melachim Alef 6:15 Meaning and Commentary

1 Kings 6:15

And he built the walls of the house within with boards of
cedar
For as yet he had only built the stone walls of it without, but now he wainscotted it with cedar boards: and not only them, but

both the floor of the house, and the walls of the ceiling;
or from "the floor of the house unto the walls of the ceiling"; that is, from the floor, including that, to the walls on each side, reaching up to the ceiling,

he covered [them] on the inside with wood:
of one sort or another, cedar or fir, or both: particularly he

covered the floor of the house with planks of fir:
which Hiram sent him, ( 1 Kings 5:8 1 Kings 5:10 ) ; which is differently interpreted; by Josephus cypress; by others, as the Tigurine version, pine tree wood; it is very probable it was of the cedar kind, and not the floor only, but the ceiling also, ( 2 Chronicles 3:5 ) .

Melachim Alef 6:15 In-Context

13 And I will dwell among the Bnei Yisroel, and will not forsake My people Yisroel.

14 So Sh’lomo built the Beis [Hamikdash], and finished it.

15 And he built the walls of the Beis [Hamikdash] within with boards of cedar, from the floor of the Beis [Hamikdash] to the rafters of the ceiling; and he covered them on the inside with wood, and covered the floor of the Beis [Hamikdash] with planks of cypress.

16 And he built twenty cubits on the sides of the Beis [Hamikdash], from the floor to the rafters with boards of cedar; he even built them for it within, even for the Debir, even for the Kodesh HaKodashim.

17 And the Beis, that is, the Heikhal in front of it, was forty cubits long.
