'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.

And he believed in the LORD; and he counted it to him for righteousness.

for I have known him, that he commandeth his children, and his house after him (and they have kept the way of Jehovah), to do righteousness and judgment, that Jehovah may bring on Abraham that which He hath spoken concerning him.'

So shall my righteousness answer for me in time to come, when it shall come for my hire before thy face: every one that is not speckled and spotted among the goats, and brown among the sheep, that shall be counted stolen with me.
