'Upright in Heart' in the Bible

But the priests were too few, so that they could not flay all the burnt-offerings: wherefore their brethren the Levites did help them, till the work was ended, and until the priests had sanctified themselves; for the Levites were more upright in heart to sanctify themselves than the priests.

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

For, lo, the wicked bend the bow, They make ready their arrow upon the string, That they may shoot in darkness at the upright in heart;

Be glad in Jehovah, and rejoice, ye righteous; And shout for joy, all ye that are upright in heart.

Oh continue thy lovingkindness unto them that know thee, And thy righteousness to the upright in heart.

The righteous shall be glad in Jehovah, and shall take refuge in him; And all the upright in heart shall glory.

For judgment shall return unto righteousness; And all the upright in heart shall follow it.

Light is sown for the righteous, And gladness for the upright in heart.
