"Did they do"

1. Mosiah 7: 28
   28 And now, because he said this, they did ^aput him to death; and many more things did they do which brought down the wrath of God upon them. Therefore, who wondereth that they are in bondage, and that they are smitten with sore afflictions?
2. 3 Ne. 4: 25
   25 And this did they do in the night-time, and got on their march beyond the robbers, so that on the morrow, when the robbers began their march, they were met by the armies of the Nephites both in their front and in their rear.
