'Upright in Heart' in the Bible

My shield is with God,Who saves the upright in heart.

For, behold, the wicked bend the bow,They make ready their arrow upon the stringTo shoot in darkness at the upright in heart.

Be glad in the Lord and rejoice, you righteous ones;And shout for joy, all you who are upright in heart.

O continue Your lovingkindness to those who know You,And Your righteousness to the upright in heart.

The righteous man will be glad in the Lord and will take refuge in Him;And all the upright in heart will glory.

For judgment will again be righteous,And all the upright in heart will follow it.

Light is sown like seed for the righteousAnd gladness for the upright in heart.
