Why does it say "ha'Omer"?
Radak: He said that he will build, and built it.
Malbim: Do not say that he did not have a house to live in. He had a house, and wanted a big house.
What is "Beis Midos"?
Rashi: It is a big house. This is like "Anshei Midos" (Bamidbar 13:32) - they have what to measure 1 . Malbim - he made it at great expense, and did not pay the workers.
There, Rashi explained that one must give a measure to them, e.g. Galyus was six Amos and a Zeres.
What are "Aliyos Meruvachim"?
Radak #1: This is like "v'Revach l'Sha'ul" (Shmuel I, 16:23), i.e. spacious.
Radak: This is based on Ru'ach (wind). They were made so wind will enter in summer.
What is the meaning of "v'Kara Lo"?
Rashi: He widened.
Rashi: Some correct 1 this and add u'Fasach Lo (he opened). This is like "Sikre'i va'Puch" (4:30), "Karata Shamayim Yaradta" (Yeshayah 63:19). Radak - Targum Yonasan is like this.
Surely, they do not change the text. They mean that it is as if it says so; the words were omitted.
What are "Chalonai"?
Radak: This is like Chalonim. Similarly, "Divrei Chozai" (Divrei ha'Yamim II, 33:19) is like Chozim (Nevi'im), and similarly "v'Orgim Chori", "va'Chashufei Shes" (Yeshayah 19:9, 20:4) and similar verses.
What is the meaning of "v'Safun ba'Arez"?
Rashi: The roof is covered with cedars. Radak - this is like "Chelkas Mechokek Safun" (Devarim 33:21), "b'Vateichem Sefunim" (Chagai 1:4).
What is the meaning of "u'Mashu'ach ba'Shashar"?
Rashi citing Targum Yonasan: [It is illustrated with dye] ingredients. Shashar is red. Mashu'ach is like Chut Shel Meshichah (Chulin 65a, a string stretched out).
Radak: Shashar is one of the colors; much of it was colored with Shashar.
