And bringing forth the people thereof he sawed them, and drove over them chariots armed with iron: and divided them with knives, and made them pass through brickkilns: so did he to all the cities of the children of Ammon: and David returned, with all the army to Jerusalem.
2 Samuel 12:29 Then David gathered all the people together, and went out against Rabbath: and after fighting, he took it.
2 Samuel 12:30 And he took the crown of their king from his head, the weight of which was a talent of gold, set with most precious stones, and it was put upon David's head, and the spoils of the city which were very great he carried away.
2 Samuel 12:31 And bringing forth the people thereof he sawed them, and drove over them chariots armed with iron: and divided them with knives, and made them pass through brickkilns: so did he to all the cities of the children of Ammon: and David returned, with all the army to Jerusalem.
The verse centers on "bringing", "forth", "people", "thereof", "sawed", "drove", "over", and "chariots". It is saying that the verse draws attention to "bringing" and "forth", so its meaning should be read from those terms before moving to application.
The prior verse says "And he took the crown of their...", giving immediate footing for "bringing" and "forth". In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "bringing" and "forth" with trust shaped by these words, not by a vague optimism outside the passage.
