What is "Makoles"?
Rashi: It is an expression of food. Radak - the Aleph (in Ma'achalos) is 'swallowed' in the Dagesh in the Kaf.
In Divrei ha'Yamim II, 2:9, Shlomo promised to give barley and wine [with the other rations]. This is not mentioned here!
Radak: Refer to 5:23:4:1.
What is "Shemen Kasis"?
Rashi: It is clean oil. The olives are not ground in a mill, rather, crushed in mortar; there are less dregs this way than when they are ground 1 .
Why is the quantity of oil a mere one part in 1000 of the quantity of wheat? In Divrei ha'Yamim II, 2:9, Shlomo promised to give 20,000 Korim of wheat and of barley for the workers who cut the trees, and a 10th of this volume of oil! (PF)
For how long did Shlomo supply this to Chiram?
Radak: It was as long as Chiram's workers worked for Shlomo.
