[3:8]  ¹ tn Heb “the house of the holy place of holy places.”

[3:8]  ⁴ tn The Hebrew word כִּכַּר (kikar, “circle”) refers generally to something that is round. When used of metals it can refer to a disk-shaped weight made of the metal or, by extension, to a standard unit of weight. According to the older (Babylonian) standard the “talent” weighed 130 lbs. (58.9 kg), but later this was lowered to 108.3 lbs. (49.1 kg). More recent research suggests the “light” standard talent was 67.3 lbs. (30.6 kg). Using this as the standard for calculation, the weight of the gold plating was 40,380 lbs. (18,360 kg).
