Albert Barnes Commentary Matthew 25:16-17

"Straightway he that received the five talents went and traded with them, and made other five talents. In like manner he also that [received] the two gained other two." — Matthew 25:16-17 (ASV)

The two who had received most employed their money in trade, and by honest industry doubled it before their master returned; representing the conduct of those who make a good improvement of their abilities, and employ them in doing good.
