Discovery Box1 Chronicles 20:3 
Context20:3 He removed the city’s residents and made them do hard labor with saws, iron picks, and axes. 1 This was his policy 2 with all the Ammonite cities. Then David and all the army returned to Jerusalem.
1 Chronicles 29:7
Context29:7 They donated for the service of God’s temple 5,000 talents 3 and ten thousand darics 4 of gold, 10,000 talents of silver, 18,000 talents of bronze, and 100,000 talents of iron.
1 tc The Hebrew text reads “saws,” but since saws were just mentioned, it is preferable to emend מְגֵרוֹת (mÿgerot, “saws”) to מַגְזְרוֹת (magzÿrot, “axes”).
2 tn Heb “and so he would do.”
3 tn See the note on the word “talents” in 19:6. Using the “light” standard talent of 67.3 lbs. (30.6 kg) as the standard for calculation, the people donated 168.3 tons (153,000 kg) of gold, 336.5 tons (306,000 kg) of silver, 605.7 tons (550,800 kg) of bronze, and 3,365 tons (3,060,000 kg) of iron.
4 tn On the “daric” as a unit of measure, see BDB 204 s.v. דַּרְכְּמוֹן. Some have regarded the daric as a minted coin, perhaps even referring to the Greek drachma, but this is less likely.
sn The daric was a unit of weight perhaps equal to between 8 and 9 grams (just under one-third of an ounce), so 10,000 darics of gold would weigh between 80 and 90 kilograms (between 176 and 198 pounds).
