'Honestly' in the Bible

No one sues righteously [but for the sake of doing injury to others—to take some undue advantage], and no one pleads [his case] in truth; [but rather]They trust in empty arguments and speak lies;They conceive trouble and bring forth injustice.

They asked Him, “Teacher, we know that You speak and teach correctly, and that You show no partiality to anyone, but teach the way of God truthfully.

just as you have [already] partially understood us, [and one day will recognize] that you can be proud of us just as we are of you, in the day of our Lord Jesus.
