'Harmless' in the Bible

Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.

for such our Lord Jesus Christ do not serve, but their own belly; and through the good word and fair speech they deceive the hearts of the harmless,

for your obedience did reach to all; I rejoice, therefore, as regards you, and I wish you to be wise, indeed, as to the good, and harmless as to the evil;

That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;

For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
