1CH 29:17

17 I know also, Elohai, that Thou doth test the levav, and hast pleasure in meisharim [(integrities, uprightness, equity)]. As for me, in the yosher levavi I have made freewill offerings of all these things, and now have I seen with simchah Thy people, which are present here, willingly offer freewill offerings unto Thee.
