And with Absalom went two hundred men out of Jerusalem, that were invited; and they went in their simplicity, and they knew nothing.

And every day, being constantly in the temple with one accord, and breaking bread in the house, they received their food with gladness and simplicity of heart,

or he that exhorts, in exhortation; he that gives, in simplicity; he that leads, with diligence; he that shews mercy, with cheerfulness.

For our boasting is this, the testimony of our conscience, that in simplicity and sincerity before God, (not in fleshly wisdom but in God's grace,) we have had our conversation in the world, and more abundantly towards you.

But I fear lest by any means, as the serpent deceived Eve by his craft, so your thoughts should be corrupted from simplicity as to the Christ.

Bondmen, obey masters according to flesh, with fear and trembling, in simplicity of your heart as to the Christ;

Bondmen, obey in all things your masters according to flesh; not with eye-services, as men-pleasers, but in simplicity of heart, fearing the Lord.
