'Blameless' in the Bible

The LORD knows the day of the blameless, and their inheritance will last forever.

Observe the blameless! Take note of the upright! Indeed, the future of that man is peace.

How blessed are those whose life is blameless, who walk in the Law of the LORD!

May my heart be blameless with respect to your statutes so that I may not become ashamed. Kaf
