'Rectitude' in the Bible

But he shall judge [the] poor with righteousness, and he shall decide for [the] needy of [the] earth with rectitude. And he shall strike [the] earth with the rod of his mouth, and he shall kill [the] wicked person with the breath of his lips.

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.

Then justice will dwell in the wilderness,And righteousness will live in the fertile field.

The Lord is exalted, for He dwells on high;He has filled Zion with justice and righteousness.

“Hear this, O house of Jacob, you who are called by the name of IsraelAnd who come from the seed of Judah,You who swear [allegiance] by the name of the LordAnd invoke the God of Israel,But not in truth (sincerity) nor in righteousness [with moral and spiritual integrity].
