What did the 70,000 carry?
Rashi: They carried rocks from the mountain to the city (Yerushalayim).
Malbim: They carried trees from Levanon in Eretz Yisrael, and from Yafo (to which Chiram sent rafts) to Yerushalayim, and carried rocks from the mountain to the place where they build [the Beis ha'Mikdash].
What is the meaning of "Nosei Sabal"?
Radak #1: They carry loads. Sabal is a noun.
Radak #2 citing Targum Yonasan: They carried on the shoulder; Sabal refers to the shoulder. It is as if it says Nosei b'Sabal, like "veha'Nos'im ba'Sevel" (Nechemyah 4:11).
Radak #3: In Divrei ha'Yamim II, 2:1 it says "Ish 1 Sabal"; it is an adjective describing the person. If it means so here, it is as if it says Nosei v'Sabal; the prefix Vov is omitted 2 . Nosei means that that they carry and move rocks in the mountain from place to place; Sabal means that they carry it on their shoulder until they reach the wagons; the wagons could not ascend the mountain.
Texts of Radak that say Nosei Sabal are mistaken. The text should say 'Ish Sabal', or just Sabal (Divrei ha'Yamim II, 2:17. - PF)
Radak: Sometimes the Vov is omitted, e.g. "Shemesh Yare'ach" (Chabakuk 3:11).
Who were the 150,000 men mentioned in the verse?
Rashi: They were all converts who converted due to Shlomo's grandeur and table 1 . Shlomo counted 153,600 converts (Divrei ha'Yamim II, 2:16).
Malbim: They are converts that David counted. Shlomo counted an additional 153,600 converts (Divrei ha'Yamim II, 2:16).
They hoped to get wealth; "Shlomo gave silver and gold in Yerushalayim like stones" (Divrei ha'Yamim II, 1:15). (PF)
