'Bond servants' in the Bible

But the father said to his servants, ‘Quickly bring out the best robe [for the guest of honor] and put it on him; and give him a ring for his hand, and sandals for his feet.

So he called ten of his servants, and gave them ten minas [one apiece, each equal to about a hundred days’ wages] and said to them, ‘Do business [with this] until I return.’

When he returned, after receiving the kingdom, he ordered that these servants, to whom he had given the money, be called to him, that he might find out what business they had done.
