'Justly' in the Bible

Roam through the streets of Jerusalem.Look and take note;search in her squares.If you find one person,any who acts justly,who seeks to be faithful,then I will forgive her.

Instead, if you really change your ways and your actions, if you act justly toward one another,

But, O Lord of hosts, who judges righteously,Who tests the feelings and the heart (mind),Let me see Your vengeance on them,For to You I have committed my cause.

For I will be with you—this is the Lord’s declaration—to save you!I will bring destruction on all the nationswhere I have scattered you;however, I will not bring destruction on you.I will discipline you justly,and I will by no means leave you unpunished.

"As for you, my servant Jacob, don't be afraid, and Israel, don't be dismayed," declares the LORD, "for I am with you. Indeed, I'll make an end of all the nations where I scattered you; but I won't make an end of you! I'll discipline you justly, but I'll certainly not leave you unpunished."
