Os justi Gregorian chant
Os justi meditabitur, Gregorian chant excerpt as it appears in Liber Usualis (1961)

Psalm 37:30, 31a, 1 [Latin]

30 The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment.

31 The law of his God is in his heart; none of his steps shall slide.

1 Fret not thyself because of evildoers, neither be thou envious against the workers of iniquity.
