According to EZK 45:14, the kor is the same as the chomer.
1KI 5:25; 1KI 5:25; 2CH 2:9; 2CH 2:9: The amount of oil which Solomon provides to Hiram is different by a factor of one hundred between these two verses. 1KI 5:25; 1KI 5:25 has “20 cors,” while the parallel text in 2CH 2:9; 2CH 2:9 has “20,000 baths.” HOTTP accepts “twenty cors” as the best reading at 1KI 5:25; 1KI 5:25 and remarks that the translator should resist the temptation to harmonize the two texts. Not all commentators and translations agree with HOTTP ’s reading, however, and some prefer to accept the Septuagint’s “20,000 baths,” which brings the two texts into line.
