'Upright in Heart' in the Bible

Only the priests were too few, and they could not flay all the burnt-offerings; therefore their brethren the Levites helped them, until the work was ended, and until the priests had hallowed themselves; for the Levites were more upright in heart to hallow themselves than the priests.

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

For behold, the wicked bend the bow, they make ready their arrow upon the string, that they may in darkness shoot at the upright in heart.

Rejoice in Jehovah, and be glad, ye righteous; and shout for joy, all ye upright in heart.

Continue thy loving-kindness unto them that know thee, and thy righteousness to the upright in heart;

The righteous shall rejoice in Jehovah, and trust 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 joy for the upright in heart.
