15  And inasmuch as ye do these things with thanksgiving, with ^bcheerful hearts and countenances, not with much laughter, for this is sin, but with a glad heart and a cheerful countenance—

  22  And after that day, I, the Lord, will not hold any guilty that shall go with an open heart up to the land of Zion; for I, the Lord, require the ^bhearts of the children of men.

  34  Behold, the Lord requireth the heart and a willing mind; and the willing and obedient shall eat the good of the land of Zion in these last days.
