'Upright' in the Bible

Then Yahweh said to me, "Apostate Israel has proved herself more upright than treacherous Judah.

You must be truthful, honest and upright when you take an oath saying, 'As surely as the Lord lives!' If you do, the nations will pray to be as blessed by him as you are and will make him the object of their boasting."

Go quickly through the streets of Jerusalem, and see now, and get knowledge, and make a search in her wide places if there is a man, if there is one in her who is upright, who keeps faith; and she will have my forgiveness.

If you are not cruel to the man from a strange country, and to the child without a father, and to the widow, and do not put the upright to death in this place, or go after other gods, causing damage to yourselves:

They are upright as the palm tree, but speak not: they must needs be borne, because they cannot go. Be not afraid of them; for they cannot do evil, neither also is it in them to do good.

But, O Lord of armies, testing the upright and seeing the thoughts and the heart, let me see your punishment come on them; for I have put my cause before you.

“Do you think that you become a king because you have much more cedar [in your palace than Solomon]?Did not your father [Josiah], as he ate and drank,Do just and righteous acts [being upright and in right standing with God]?Then all was well with him.
