'Upright' in the Bible

The way of the righteous [those in right-standing with God—living in moral and spiritual integrity] is smooth and level;O Upright One, make a level path for the just and righteous.

This is what the Lord who made youAnd formed you from the womb, who will help you says,‘Fear not, O Jacob My servant;And Jeshurun (Israel, the upright one) whom I have chosen.

As a result of the anguish of His soul,He shall see it and be satisfied;By His knowledge [of what He has accomplished] the Righteous One,My Servant, shall justify the many [making them righteous—upright before God, in right standing with Him],For He shall bear [the responsibility for] their sins.

The righteous man perishes [at the hand of evil], and no one takes it to heart;Faithful and devout men are taken away, while no one understandsThat the righteous person is taken away [to be spared] from disaster and evil.
