'Sold' in the Bible

Aren't two sparrows sold for a penny? Yet not one of them falls to the ground apart from your Father's will.

"The kingdom of heaven is like a treasure, hidden in a field, that a person found and hid. Then because of joy he went and sold all that he had and bought that field.

When he found a pearl of great value, he went out and sold everything he had and bought it.

Because he was not able to repay it, the lord ordered him to be sold, along with his wife, children, and whatever he possessed, and repayment to be made.

It could have been sold at a high price and the money given to the poor!"
