'Righteousness' in the Bible

Yahweh said to Noah, "Come with all of your household into the ship, for I have seen your righteousness before me in this generation.

He believed in Yahweh; and he reckoned it to him for righteousness.

For I have known him, to the end that he may command his children and his household after him, that they may keep the way of Yahweh, to do righteousness and justice; to the end that Yahweh may bring on Abraham that which he has spoken of him."

So my righteousness will answer for me hereafter, when you come concerning my hire that is before you. Every one that is not speckled and spotted among the goats, and black among the sheep, that might be with me, will be counted stolen."
