'Upright' in the Bible

These are the words of the Lord: For three crimes of Israel, and for four, I will not let its fate be changed; because they have given the upright man for silver, and the poor for the price of two shoes;

They have hate for him who makes protest against evil in the public place, and he whose words are upright is disgusting to them.

For I have seen how your evil-doing is increased and how strong are your sins, you troublers of the upright, who take rewards and do wrong to the cause of the poor in the public place.
