'Blameless' in the Bible

This is the history of the generations of Noah. Noah was a righteous man, blameless among the people of his time. Noah walked with God.

When Abram was ninety-nine years old, Yahweh appeared to Abram, and said to him, "I am God Almighty. Walk before me, and be blameless.

He said, "Now also let it be according to your words: he with whom it is found will be my bondservant; and you will be blameless."
