'Gladness' in the Bible

Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows.

Obey your [spiritual] leaders and submit to them [recognizing their authority over you], for they are keeping watch over your souls and continually guarding your spiritual welfare as those who will give an account [of their stewardship of you]. Let them do this with joy and not with grief and groans, for this would be of no benefit to you.
