1 Chronicles 29:17

I know also, my God, that thou triest the heart
Searchest it, and knowest it perfectly, whether what is done is from it:

and hast pleasure in uprightness;
in what is done in sincerity and uprightness of heart:

as for me, in the uprightness of my heart I have willingly offered all
these things;
for the truth of which he could appeal to the heart searching God:

and now have I seen with joy thy people, which are present here, to
offer willingly unto thee;
he judged by what they did, and their manner of doing it, that it was done in the uprightness of their hearts also, as his were, which gave him sensible joy and pleasure.
