'Blamelessly' in the Bible

He who walks blamelessly does what is right, and speaks truth in his heart;

Do you indeed speak righteousness, silent ones? Do you judge blamelessly, you sons of men?

When I choose the appointed time, I will judge blamelessly.

For Yahweh God is a sun and a shield. Yahweh will give grace and glory. He withholds no good thing from those who walk blamelessly.
