The Lent 3 Offertory: Iustitiae Domini ("The judgements of the Lord")

Iustitiae Domini is the beautiful Offertory for the 3rd Sunday in Lent, sung here by the Nova Schola Gregoriana:



This is the English translation of this chant, from Prosper Gueringer 's book on the Liturgical Year:

The justices of the Lord are right, rejoicing hearts; his ordinances are sweeter than honey and the honey-comb: therefore thy servant observeth them.

(Another, better translation of "justices" there might be "judgements," or "just decrees."  I do believe Iustitiae is plural.)

The text comes from Psalm (18/)19: vv. 9 - 11:

9 the fear of the Lord is clean,
    enduring forever;
the rules[d] of the Lord are true,
    and righteous altogether.
10 More to be desired are they than gold,
    even much fine gold;
sweeter also than honey
    and drippings of the honeycomb.
11 Moreover, by them is your servant warned;
    in keeping them there is great reward.

Here's the chant score:

There is more in the video than just what's included on this score; I'm still trying to work out what it is, and where it came from.

Here's something from Wikipedia about Psalm 19:

Psalm 19 is the 19th psalm in the Book of Psalms (the 18th in the Septuagint numbering). It is ascribed to David.

The psalm considers the glory of God in creation, and moves to reflect on the character and use of "the law of the LORD". A comparison is made between the law and the sun, which lends a degree of unity to the psalm. C. S. Lewis suggested that in verse 7, the Psalmist starts talking about something else, "which hardly seems to him like something else because it is so like the all-piercing, all-detecting sunshine."^[1] Like the Sun, the law is able to uncover hidden faults, and nothing can hide from it. As the Psalmist meditates on the excellencies of the law, he feels that his sins have been laid open before God's word, and asks for forgiveness and help.

Verses 7–11: The law – sweeter than honey

Psalm 19:7 The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple.
8 The statutes of the LORD are right, rejoicing the heart: the commandment of the LORD is pure, enlightening the eyes.
9 The fear of the LORD is clean, enduring for ever: the judgments of the LORD are true and righteous altogether.
10 More to be desired are they than gold, yea, than much fine gold: sweeter also than honey and the honeycomb.
11 Moreover by them is thy servant warned: and in keeping of them there is great reward.

— Psalm 19:7–11 King James Version
Psalm 19:7-11 Other versions

In verses 7–11 the law of the LORD, that is the Torah, is presented as another source of revelation about God's character and expectations. The instructions are referred to as "direct" from the Hebrew yesharim meaning to make straight, smooth, right or upright. One commentator's^[7] interpretation indicates that since this law shows a person what to do and keep in mind, what to avoid, how to please God, and what help he can expect from God, they are highly desirable and valuable.

The description of the law as radiant and enlightening ties the earlier references to the lights of nature to the character of God and to his laws as revealing truths.^[2] The Torah is associated with light in other passages as well, such as Proverbs 6:23 "For the commandment is a lamp; and the law is light; and reproofs of instruction are the way of life:"
