to be in the right: to stand righteous, just, or cleared, whether as a settled state of life or as a verdict won in a dispute
This is the verb seen from the side of the person whose standing is at stake. Two shades belong together here. One is the steady condition of being a person who is in the right, whose life lines up with what God requires. The other is the moment that condition is recognized: the one who is in the right is proved right, cleared, and vindicated when the matter is tested or contested.
The book of Job presses the first shade to its limit, asking again and again whether any human being can really be in the right when measured against God. Job insists he is; his friends, and finally God, force the question open. The same word then carries the second shade in the courtroom and the prophets: when a charge is laid and answered, the innocent party is shown to be in the right.
The two run together because in Hebrew thought being righteous and being vindicated are not separate worlds. To be in the right is already to have a claim that, fairly heard, will be upheld. The word can name the standing and the recognition of it in one breath.
