'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 other priests had sanctified themselves: for the Levites were more upright in heart to sanctify themselves than the priests.

My defence is of God, which saveth the upright in heart.

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

Be glad in the LORD, and rejoice, ye righteous: and shout for joy, all ye that are upright in heart.

O continue thy lovingkindness unto them that know thee; and thy righteousness to the upright in heart.

The righteous shall be glad in the LORD, and shall trust in him; and all the upright in heart shall glory.

But 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.
