'Blameless' in the Bible

I was blameless before Him,And I kept myself free from my sin.

Also keep back Your servant from presumptuous (deliberate, willful) sins;Let them not rule and have control over me.Then I will be blameless (complete),And I shall be acquitted of great transgression.

The wicked have drawn the sword and bent their bowTo cast down the afflicted and the needy,To slaughter those who are upright in conduct [those with personal integrity and godly character].

The Lord knows the days of the blameless,And their inheritance will continue forever.

Mark the blameless man [who is spiritually complete], and behold the upright [who walks in moral integrity];There is a [good] future for the man of peace [because a life of honor blesses one’s descendants].

To shoot from ambush at the blameless [one];Suddenly they shoot at him, without fear.

I will behave wisely and follow the way of integrity.When will You come to me?I will walk in my house in integrity and with a blameless heart.

How blessed and favored by God are those whose way is blameless [those with personal integrity, the upright, the guileless],Who walk in the law [and who are guided by the precepts and revealed will] of the Lord.

May my heart be blameless in Your statutes,So that I will not be ashamed.
