Ps 19:4

“"Diapsalma." The Lord render to Thee according to Thine Heart" (ver. 4). The Lord render to Thee, not according to their heart, who thought by persecution they could destroy Thee; but according to Thine Heart, wherein Thou knewest what profit Thy passion would have. "And fulfil all Thy counsel." "And fulfil all Thy counsel," not only that whereby Thou didst lay down Thy life for Thy friends, that the corrupted grain might rise again to more abundance; but that also whereby "blindness in part hath happened unto Israel, that the fulness of the Gentiles might enter in, and so an Israel might be saved."”

“The third counsel is that by which we are made ready to pursue what is lawful, what is fitting, and what is expedient according to the exercise of virtuous operation. What you have well conceived in mind, you may bring to completion in deed. The Psalm says: 'May he grant you according to your heart and confirm all your counsel.' That counsel adds over and above readiness for action. There is a threefold operation, namely to discern rightly, to choose well, and to pursue readily.”

“"May he grant." Above, the Psalmist asked in prayer for promotion to good, which is the outwardly desired good; here he asks for that good which is inwardly sought: and concerning this he does two things. First he asks that what he requests be fulfilled. Second he sets forth the reason, at "We shall rejoice." Concerning the first he does two things. First he asks for that which is in the interior movement of the soul, according to the will of the end. Second he asks that the counsel concerning the things which are directed to the end be fulfilled: "And may he confirm all your counsel," etc. He says, therefore, "May he grant you according to your heart," that is, according to the will which is directed to the end; as if to say, may he lead you to the end you intend, which ought to be God: Prov. 10: "The desire of the just shall be granted." "And may he confirm all your counsel"; this concerns the things that are directed to the end (...) for our counsels are weak, because we cannot foresee all things: Wis. 9: "The thoughts of mortals are timid, and our foresight is uncertain." But God is the one who confirms by directing our counsel, which ought to be about seeking eternal things: Jn. 16: "Ask, that your joy may be full": and by giving efficacy to carry out our counsels. But he scatters the counsel of the wicked, as it is said in Job 5.”

“Sacrifices. Hebrew mincha, a sacrifice of flour, or unbloody; a figure of the Mass. (Worthington) — Minchothec, “thy presents” (Mont.; Haydock) of fruits, &c. — Fat. Hebrew also, “ashes,” by miraculous fire, (Berthier) to testify God’s acceptance; as at the sacrifices of Abel, (Haydock) Elias, &c., Leviticus ix. 24., and 3 Kings xviii. 31., and 1 Paralipomenon xxi. 26. God forbade lean victims to be offered, as they might shew a want of respect; (Malachias i. 8.) though he always regarded the heart (Calmet) and faith of the offerer more than the victim, Hebrews xi. 4. (Haydock) — Sacrifices were offered before every important enterprize, 1 Kings xiii. 12. (Calmet) — Fat here intimates what would be acceptable. (Worthington) (Daniel iii. 40.) (Menochius)”
