Ps 49:5

“"Gather to Him His righteous" [Psalm 50:5]. The voice divine and prophetic, seeing future things as if present doth exhort the Angels gathering. For He shall send His Angels, and before Him shall be gathered all nations. Gather to Him His righteous. What righteous men save those that live of faith and do works of mercy? For those works are works of righteousness. Thou hast the Gospel: "Beware of doing your righteousness before men to be seen of them." And as if it were inquired, What righteousness? "When therefore thou doest alms," He saith. Therefore alms He hath signified to be works of righteousness. Those very persons gather for His righteous: gather those that have had compassion on the "needy," that have considered the needy and poor: gather them, "The Lord preserve them, and make them to live;" "Gather to Him His righteous: who order His covenant above sacrifices:" that is, who think of His promises above those things which they work. For those things are sacrifices, God saying, "I will have mercy more than sacrifice." "Who keep His covenant more than sacrifice."”

“Gather to Me My devoted ones And He will further call to the heavens and the earth that they gather the exiles to Him, as the matter that is stated (Song 4:16): “Awake, O north wind, and come, O south wind.” who made a covenant with Me over a sacrifice Who received the Torah with a covenant and a sacrifice, as it is stated (Exod. 24:8): “Behold the blood of the covenant, which the Lord has made with you.””

Hebrew, “my merciful ones,” (Haydock) the chosen people, (Calmet) particularly priests, (Theodoret) who might have too high an opinion of the legal sacrifices, (St. Chrysostom) or all the elect are meant, Matthew xxiv. 30. (Eusebius) — The Hebrews were the only nation which then offered sacrifices to the true God, though some individuals might do it among the Gentiles. (Calmet) — Before, super, or, “who make a covenant with him respecting sacrifices.” — Protestants, “those that have made a covenant with me by sacrifice,” Malachias i. 12. (Haydock) — The Septuagint seem to have read v for i, more accurately, as the prophet speaks till ver. 7. (Berthier) — Judgment should begin at the house of God. And if first at us, what shall be the end of them that believe not the gospel of God? (1 Peter iv. 17., and Romans ii. 9.) (Haydock) — Those who believe not, are already judged, John iii. — Sacrifice generally precedes a covenant, Genesis xv. 17. (Menochius)”
