1 Chronicles 20:3

20:3 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 21:16

21:16 David looked up and saw the Lord’s messenger standing between the earth and sky with his sword drawn and in his hand, stretched out over Jerusalem. David and the leaders, covered with sackcloth, threw themselves down with their faces to the ground. ³ 

[20:3]  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”).

[20:3]  ² tn Heb “and so he would do.”

[21:16]  ³ tn Heb “and David and the elders, covered with sackcloth, fell on their faces.”
