2 Chronicles 4:2

4:2 He also made the big bronze basin called “The Sea.” ¹  It measured 15 feet ²  from rim to rim, was circular in shape, and stood seven and one-half feet ³  high. Its circumference was 45 feet. ⁴ 

2 Chronicles 4:5

4:5 It was four fingers thick and its rim was like that of a cup shaped like a lily blossom. It could hold 18,000 gallons. ⁵ 

[4:2]  ¹ tn Heb “He made the sea, cast.”

[4:2]  ² tn Heb “ten cubits.” Assuming a cubit of 18 inches (45 cm), the diameter would have been 15 feet (4.5 m).

[4:2]  ³ tn Heb “five cubits.” Assuming a cubit of 18 inches (45 cm), the height would have been 7.5 feet (2.25 m).

[4:2]  ⁴ tn Heb “and a measuring line went around it thirty cubits all around.”

[4:5]  ⁵ tn Heb “3,000 baths” (note that the capacity is given in 1 Kings 7:26 as “2,000 baths”). A bath was a liquid measure roughly equivalent to six gallons (about 22 liters), so 3,000 baths was a quantity of about 18,000 gallons (66,000 liters).
